Check Digit Verification of cas no

The CAS Registry Mumber 6911-51-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,1 and 1 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6911-51:
(6*6)+(5*9)+(4*1)+(3*1)+(2*5)+(1*1)=99
99 % 10 = 9
So 6911-51-9 is a valid CAS Registry Number.

Organic Metals: Conducting Complexes of Poly(2,5-thienylene sulphide) and Poly(2,5-thienylene selenide)

Jen, Kwan-Yue,Benfaremo, Nicholas,Cava, Michael P.,Huang, Wu-Song,MacDiarmid, A. G.

, p. 633 - 634 (1983)

Exposure of highly purified samples of the new polymers poly(2,5-thienylene selenide) (PTSe) and poly(2,5-thienylene sulphide) (PTS) to arsenic pentafluoride afforded a conducting complex (0.12 S/cm) from PTSe but only a moderately conducting complex (ca. 10-5 S/cm) from PTS, a result which is in direct contrast to the behaviour of poly(p-phenylene selenide) and poly(p-phenylene sulphide) upon similar treatment.

Metal-free chalcogenation of cycloketone oxime esters with dichalcogenides

Ji, Liangshuo,Qiao, Jiamin,Liu, Junjie,Tian, Miaomiao,Lu, Kui,Zhao, Xia

supporting information, (2021/06/15)

We report the metal-free chalcogenation of cycloketone oxime esters with dichalcogenides via a radical process. Because of the metal-free condition and use of readily accessible dichalcogenides, this method is an effective and green strategy for the synthesis of chalcogen-substituted butyronitrile.

Copper-catalyzedortho-selective direct sulfenylation ofN-aryl-7-azaindoles with disulfides

Ru-Jian, Yu,Chun-Yan, Zhang,Xiang, Zhou,Xiong, Yan-Shi,Duan, Xue-Min

supporting information, p. 2901 - 2906 (2021/04/14)

A copper-catalyzed direct C-H chalcogenation ofN-aryl-azaindoles with disulfides is described. This transformation was performed using Earth abundant Cu(OAc)2as a catalyst, benzoic acid as an additive, air as a terminal oxidant, and readily available diaryl and dialkyldisulfides (or diselenide) as chalcogenation reagents. High functional group tolerance and excellent regioselectivity are demonstrated by the efficient preparation of a wide range ofortho-sulfenylation-7-azaindoles.

Sequential C-H activation enabled expedient delivery of polyfunctional arenes

Cai, Xiaoqing,Chen, Qian,Chen, Xiaojian,Gao, Yang,Huo, Yanping,Li, Xianwei,Ouyang, Wensen,Rao, Jianhang,Wang, Jie

supporting information, p. 8075 - 8078 (2021/08/20)

Modular construction of polyfunctional arenes from abundant feedstocks stands as an unremitting pursue in synthetic chemistry, accelerating the discovery of drugs and materials. Herein, using the multiple C-H activation strategy with versatile imidate esters, the expedient delivery of molecular libraries of densely functionalized sulfur-containing arenes was achieved, which enabled the concise construction of biologically active molecules, such as Bipenamol.

Dual Roles of Rongalite: Reductive Coupling Reaction to Construct Thiosulfonates Using Sulfonyl Hydrazides

Zhang, Guofu,Fan, Qiankun,Zhao, Yiyong,Wang, Huimin,Ding, Chengrong

supporting information, p. 81 - 85 (2020/11/03)

A tunable and practical transformation of structurally diverse sulfonyl hydrazides into thiosulfonates in the presence of Rongalite (NaHSO 2·CH 2O) was developed. Transition-metal-free conditions, operational simplicity, and readily available reagents are the striking features of this protocol. It is the first example for the synthesis of thiosulfonates using sulfonyl hydrazides with the assistance of reductant. Additionally, the mechanistic studies revealed that this transformation probably undergoes via a reducing-coupling pathway.

Development of disulfide-derived fructose-1,6-bisphosphatase (FBPase) covalent inhibitors for the treatment of type 2 diabetes

Xu, Yi-xiang,Huang, Yun-yuan,Song, Rong-rong,Ren, Yan-liang,Chen, Xin,Zhang, Chao,Mao, Fei,Li, Xiao-kang,Zhu, Jin,Ni, Shuai-shuai,Wan, Jian,Li, Jian

, (2020/07/25)

Fructose-1,6-bisphosphatase (FBPase), as a key rate-limiting enzyme in the gluconeogenesis (GNG) pathway, represents a practical therapeutic strategy for type 2 diabetes (T2D). Our previous work first identified cysteine residue 128 (C128) was an important allosteric site in the structure of FBPase, while pharmacologically targeting C128 attenuated the catalytic ability of FBPase. Herein, ten approved cysteine covalent drugs were selected for exploring FBPase inhibitory activities, and the alcohol deterrent disulfiram displayed superior inhibitory efficacy among those drugs. Based on the structure of lead compound disulfiram, 58 disulfide-derived compounds were designed and synthesized for investigating FBPase inhibitory activities. Optimal compound 3a exhibited significant FBPase inhibition and glucose-lowering efficacy in vitro and in vivo. Furthermore, 3a covalently modified the C128 site, and then regulated the N125–S124–S123 allosteric pathway of FBPase in mechanism. In summary, 3a has the potential to be a novel FBPase inhibitor for T2D therapy.

Natural gallic acid catalyzed aerobic oxidative coupling with the assistance of MnCO3 for synthesis of disulfanes in water

Song, Lijuan,Li, Wenhao,Duan, Wenxue,An, Jichao,Tang, Shanyu,Li, Longjia,Yang, Guanyu

supporting information, p. 1432 - 1438 (2019/03/26)

The formation of S-S bonds has great significance and value in synthetic chemistry and bioscience. To pursue a sustainable approach for such a synthesis, an aerobic oxidative coupling method for the efficient preparation of organic disulfanes, using a low-toxic natural gallic acid as an organocatalyst, inexpensive MnCO3 as a cocatalyst, O2 as the terminal oxidant and water as the solvent, has been successfully developed. Such metal-organic cooperative catalytic protocol provided an access to various symmetrical and unsymmetrical disulfanes in up to 99% yield. Gram scale synthesis with practical convenience and low loading of catalysts further illustrates the practicability of our method.

An Organodiselenide with Dual Mimic Function of Sulfhydryl Oxidases and Glutathione Peroxidases: Aerial Oxidation of Organothiols to Organodisulfides

Rathore, Vandana,Upadhyay, Aditya,Kumar, Sangit

supporting information, p. 6274 - 6278 (2018/10/05)

A novel organodiselenide, which mimics sulfhydryl oxidases and glutathione peroxidase (GPx) enzymes for oxidation of thiols by oxygen and hydrogen peroxide, respectively, into disulfides has been presented. The developed catalyst oxidizes an array of organothiols into respective disulfides in practical yields by using aerial O2 to avoid any reagents/additives, base, and light source. The synthesized diselenide also catalyzes the reduction of hydrogen peroxide into water by following the GPx enzymatic catalytic cycle with a reduction rate of 49.65 ± 3.7 μM·min-1.

Soleiman-Beigi, Mohammad,Mohammadi, Keivan,Mohammadi, Fariba

, p. 1545 - 1550 (2018/06/21)

A simple, one-pot, efficient and novel protocol has been developed for direct synthesis of symmetrical organic disulfides by domino reaction of aryl halides and K2S in the presence of magnetic Fe3O4 nanoparticles as a readily available, highly efficient and recyclable catalyst. A variety of diaryl disulfides can be obtained in good-to-excellent yields up to 98%.

-

Paragraph 0022; 0023; 0029; 0030, (2017/08/29)

The invention provides a method for catalyzing molecular oxygen to oxidize into disulfides with S-S bonds in an aqueous phase. The method includes taking water-soluble transition metal phthalocyanine compounds as catalysts, and enabling sulfhydryl compounds to react for 1-30 hours in the aqueous phase at a pressure of 0.01-1.00 Mpa, at 40-100 DEG C and in the presence of oxygen or air so as to obtain the disulfides with the S-S bonds. The method has the advantages that reaction is conducted in the aqueous phase, so that addition of other organic solvents is unneeded; the catalysts are high in catalytic activity, high in reaction efficiency and reusable; the method is simple in synthetic process, high in product selectivity, fewer in byproducts and wastes and environment friendly, thereby being promising in industrial application prospect.
