Check Digit Verification of cas no

The CAS Registry Mumber 6738-23-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,3 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6738-23:
(6*6)+(5*7)+(4*3)+(3*8)+(2*2)+(1*3)=114
114 % 10 = 4
So 6738-23-4 is a valid CAS Registry Number.

Preparation method of nitrogen-alkyl (deuterated alkyl) aromatic heterocycle and alkyl (deuterated alkyl) aryl ether compound

-

Paragraph 0093-0098, (2021/04/03)

The invention provides a method for preparing nitrogen-alkyl(deuterated alkyl)aromatic heterocycle and alkyl(deuterated alkyl)aryl ether compounds. The method adopted in the invention specifically comprises the following steps: firstly, adding an alkoxy base (MOR') or a combination reagent Q (comprising a base M'X, an alcohol C and a molecular sieve E) into a solvent B to be stirred; then, addingan aromatic compound D of nitrogen sulfonyl or oxygen sulfonyl into a mixture; separating and purifying after reaction to obtain nitrogen-alkyl(deuterated alkyl)aromatic heterocycle or alkyl(deuterated alkyl)aryl ether. The method can realize one-step conversion from an electron withdrawing benzenesulfonyl protecting group on a nitrogen or oxygen atom to an electron donating alkyl protecting group, avoids using highly toxic alkyl halide, and has advantages of being efficient, economical, environmentally friendly, mild in condition, good in substrate universality and high in yield; the prepareddeuterated compounds can be widely applied to the fields of pharmaceutical chemistry and organic chemistry synthesis.

Electro-Oxidative Selective Esterification of Methylarenes and Benzaldehydes

Yu, Congjun,?zkaya, Bünyamin,Patureau, Frederic W.

supporting information, p. 3682 - 3687 (2021/02/01)

A mild and green electro-oxidative protocol to construct aromatic esters from methylarenes and alcohols is herein reported. Importantly, the reaction is free of metals, chemical oxidants, bases, acids, and operates at room temperature. Moreover, the design of the electrolyte was found critical for the oxidation state and structure of the coupling products, a rarely documented effect. This electro-oxidative coupling process also displays exceptional tolerance of many fragile easily oxidized functional groups such as hydroxy, aldehyde, olefin, alkyne, as well as neighboring benzylic positions. The enantiomeric enrichment of some chiral alcohols is moreover preserved during this electro-oxidative coupling reaction, making it overall a promising synthetic tool.

Synthesis and in vitro activities on anti-platelet aggregation of 4-methoxy-1,3-phthalamidesamides and benzenedisulfonamides

Chen, Guangling,Wang, Chaoqing,Zhang, Zhihao,Liu, Xiujie

, p. 1413 - 1424 (2019/06/20)

Cardiovascular diseases are the most frequent cause of morbidity and mortality worldwide. In order to discover novel compounds with anti-platelet aggregation activities, a series of novel 4-methoxy-1,3-phthalamidesamides (1a–1i) and a series of novel 4-methoxy-1,3-benzenedisulfon-amides (2a–2i) were synthesized and their anti-platelet aggregation activities were evaluated by the turbidimetric method in response to the following agonists: adenosine diphosphate (ADP), arachidonic acid (AA), and Collagen. Those compounds that have better in vitro activities were subjected to cell toxicity tests via cell counting kit-8 (CCK-8) assay. The inhibition rates of anti-platelet in vitro of five compounds 1g (39.45%), 2d (38.87%), 2g (38.55%), 2h (44.56%), and 2i (43.93%) were higher than that of two reference drugs picotamide (36.12%) and aspirin (38.45%) when ADP was selected as an inducer. The inhibition rates of seven compounds 1c (43.63%), 1d (40.02%), 1g (47.42%), 1i (40.45%), 2c (40.11%), 2d (40.45%), and 2i (49.05%) were higher than that of picotamide (34.89%) and aspirin (39.43%) when AA was selected as inducer. And the inhibition rates of five compounds 1d (47.22%), 1i (45.01%), 2d (38.74%), 2e (42.21%), and 2f (39.94%) were higher than picotamide (38.45%) and aspirin (37.08%) when collagen was selected as inducer. Moreover, the effect of cell toxicity exhibited that none of the compounds had obvious cell toxicity against L-929 cells. Therefore, 4-methoxy-1,3-phthalamidesamides (1a–1i) and 4-methoxy-1,3-benzenedisulfon-amides (2a–2i) have the potential to become a novel kind of anti-platelet drugs and deserve further study.

Detosylative (Deutero)alkylation of Indoles and Phenols with (Deutero)alkoxides

Zhu, Ming-Hui,Yu, Cheng-Long,Feng, Ya-Lan,Usman, Muhammad,Zhong, Dayou,Wang, Xin,Nesnas, Nasri,Liu, Wen-Bo

supporting information, p. 7073 - 7077 (2019/09/30)

An efficient strategy for N/O-(deutero)alkylation of indoles and phenols with alkoxides/alcohols as the alkylation reagents is described. The consecutive detosylation/alkylation transformations feature mild reaction conditions, high ipso-selectivity, and good functional group tolerance (>50 examples). A one-pot selective N-alkylation of unprotected indoles with alcohols and TsCl is also realized. The application of this method is demonstrated by the introduction of isotope-labeled (CD3 and 13CH3) groups using the readily accessible labeled alcohols and the synthesis of pharmaceuticals.

4,5-Dimethyl-2-Iodoxybenzenesulfonic Acid Catalyzed Site-Selective Oxidation of 2-Substituted Phenols to 1,2-Quinols

Uyanik, Muhammet,Mutsuga, Tatsuya,Ishihara, Kazuaki

supporting information, p. 3956 - 3960 (2017/03/27)

A site-selective hydroxylative dearomatization of 2-substituted phenols to either 1,2-benzoquinols or their cyclodimers, catalyzed by 4,5-dimethyl-2-iodoxybenzenesulfonic acid with Oxone, has been developed. Natural products such as biscarvacrol and lacinilene C methyl ether could be synthesized efficiently under mild reaction conditions. Furthermore, both the reaction rate and site selectivity could be further improved by the introduction of a trialkylsilylmethyl substituent at the 2-position of phenols. The corresponding 1,2-quinols could be transformed into various useful structural motifs by [4+2] cycloaddition cascade reactions.
