Check Digit Verification of cas no

The CAS Registry Mumber 23355-97-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,3,5 and 5 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 23355-97:
(7*2)+(6*3)+(5*3)+(4*5)+(3*5)+(2*9)+(1*7)=107
107 % 10 = 7
So 23355-97-7 is a valid CAS Registry Number.

Molybdenum(VI) cis-dioxo complexes bearing sugar derived chiral Schiff-base ligands: Synthesis, characterization, and catalytic applications

Zhao, Jin,Zhou, Xiangge,Santos, Ana M.,Herdtweck, Eberhardt,Romao, Carlos C.,Kuehn, Fritz E.

, p. 3736 - 3742 (2003)

Molybdenum(VI)-cis-dioxo complexes bearing sugar derived chiral Schiff-base ligands of general formula MoO2(L)(Solv) have been synthesized (with L = N-salicylidene-D-glucosamine; N-salicylidene-1,3,4,6-tetraacetyl-α-D-glucosamine; N-5-chlorosal

Synthesis of a Fe3O4-CuO@meso-SiO2 nanostructure as a magnetically recyclable and efficient catalyst for styrene epoxidation

Zhang, Xiaowei,Wang, Ge,Yang, Mu,Luan, Yi,Dong, Wenjun,Dang, Rui,Gao, Hongyi,Yu, Jie

, p. 3082 - 3089 (2014)

A novel hybrid Fe3O4-CuO@meso-SiO2 catalyst was successfully fabricated by a multi-step assembly method. CuO nanoparticles were first deposited on the surface of Fe3O4 microspheres to form the Fe

Chiral ansa-bridged η5-cyclopentadienyl molybdenum complexes: Synthesis, structure and application in asymmetric olefin epoxidation

Zhao, Jin,Herdtweck, Eberhardt,Kühn, Fritz E.

, p. 2199 - 2206 (2006)

Ansa-bridged η5-cyclopentadienyl carbonyl molybdenum complexes were synthesized with stereogenic centers located in the side chain. An exemplary X-ray crystal structure and the catalytic activity for asymmetric olefin epoxidation are reported. In non-chiral epoxidation the compounds show a good catalytic activity, comparable to activities observed for the related non-chiral complexes of composition CpMo(CO)3X (X = Cl, CH3). For the asymmetric epoxidation of trans-β-methylstyrene the chiral induction is up to ca. 20%. The high ring strain of the ansa-bridged system hampers, unfortunately, its stability under oxidative condition.

Polymer-bound chiral (salen)Mn(III) complex as heterogeneous catalyst in rapid and clean enantioselective epoxidation of unfunctionalised olefins

Minutolo, Filippo,Pini, Dario,Salvadori, Piero

, p. 3375 - 3378 (1996)

The application of a new polystyrene-divinylbenzene system containing an optically active (salen)Mn(III) complex in asymmetric epoxidation of unfunctionalised olefins is reported. This system showed a remarkably high reaction speed in the conditions descr

High-yield epoxidations with hydrogen peroxide and tert-butyl hydroperoxide catalyzed by iron(III) porphyrins: Heterolytic cleavage of hydroperoxides

Traylor, Teddy G.,Tsuchiya, Shinji,Byun, Young-Seok,Kim, Cheal

, p. 2775 - 2781 (1993)

The reactions of hydrogen peroxide or tert-butyl hydroperoxide with cyclooctene and norbornene, catalyzed by iron(III) tetrakis(pentafluorophenyl)porphyrin chloride and other electronegatively-substituted porphyrins, produce 60-100% epoxide yields. The ep

Enantioselective, Stereoconvergent Resolution Copolymerization of Racemic cis-Internal Epoxides and Anhydrides

He, Guang-Hui,Ren, Bai-Hao,Chen, Shi-Yu,Liu, Ye,Lu, Xiao-Bing

, p. 5994 - 6002 (2021/02/11)

Unprecedented enantioselective resolution copolymerization of racemic cis-internal epoxides and anhydrides was mediated by dinuclear aluminum complexes with multiple chirality, affording optically active polyesters with two contiguous stereogenic centers, and the unreacted substrates in good enantioselectivity. Unexpected stereoconvergence is observed in this resolution copolymerization, where the selectivity factor for the enantioselective formation of copolymer significantly exceeds the kinetic resolution coefficient based on the unreacted epoxide at various conversions. Catalytic activity and copolymer enantioselectivity are strongly influenced by the phenolate ortho-substituents of the ligand set, as well as the axial linker and its chirality. An enantiopure binaphthol-linked bimetallic AlIII complex allows stereoconvergent access to the stereoregular semi-crystalline polyesters and a concomitant kinetic resolution of the epoxide substrates.

Kinetic resolution ofN-aryl β-amino alcoholsviaasymmetric aminations of anilines

Guo, Zheng,Xie, Jinglei,Hu, Tao,Chen, Yunrong,Tao, Houchao,Yang, Xiaoyu

supporting information, p. 9394 - 9397 (2021/09/22)

An efficient kinetic resolution ofN-aryl β-amino alcohols has been developedviaasymmetricpara-aminations of anilines with azodicarboxylates enabled by chiral phosphoric acid catalysis. Broad substrate scope and high kinetic resolution performances were afforded with this method. Control experiments supported the critical roles of the NH and OH group in these reactions.
