211230-12-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 211230-12-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,1,2,3 and 0 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 211230-12:
(8*2)+(7*1)+(6*1)+(5*2)+(4*3)+(3*0)+(2*1)+(1*2)=55
55 % 10 = 5
So 211230-12-5 is a valid CAS Registry Number.

Copper hydride catalyzed enantioselective conjugate reduction of unsaturated nitriles

Lee, Daehyung,Yang, Youngmin,Yun, Jaesook

, p. 2233 - 2235 (2007)

α,β-Unsaturated nitriles were reduced with high levels of enantioselectivity via copper hydride catalysis. In this procedure, bench-top stable copper(II) acetate and Josiphos ligand are used as the chiral catalyst and an inexpensive hydrosilane, polymethy

Asymmetric Umpolung Hydrogenation and Deuteration of Alkenes Catalyzed by Nickel

Guo, Siyu,Wang, Xiuhua,Zhou, Jianrong Steve

supporting information, p. 1204 - 1207 (2020/02/04)

Nickel-catalyzed asymmetric hydrogenation of several types of alkenes proceeds in high enantioselectivity, using acetic acid or water as the hydrogen source and indium powder as electron donor. The scope of alkenes herein include α,β-unsaturated esters, n

Highly efficient Rh-catalyzed asymmetric hydrogenation of α,β-unsaturated nitriles

Yan, Qiaozhi,Kong, Duanyang,Li, Meina,Hou, Guohua,Zi, Guofu

, p. 10177 - 10181 (2015/09/01)

A highly efficient enantioselective hydrogenation of α,β-unsaturated nitriles catalyzed by Rh-(R,R)-f-spiroPhos complex has been developed. With Rh-(R,R)-f-spiroPhos catalyst and under mild conditions, a wide range of α,β-unsaturated nitriles including the (E)- and (Z)-isomers of 3-alkyl-3-aryl, 3,3-diaryl, and 3,3-dialkyl α,β-unsaturated nitriles were hydrogenated to the corresponding chiral nitriles with excellent enantioselectivities (up to 99.9% ee) and high turnover numbers (TON up to 10,000).
