Check Digit Verification of cas no

The CAS Registry Mumber 1620697-57-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,6,9 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1620697-57:
(9*1)+(8*6)+(7*2)+(6*0)+(5*6)+(4*9)+(3*7)+(2*5)+(1*7)=175
175 % 10 = 5
So 1620697-57-5 is a valid CAS Registry Number.

Highly enantioselective hydrogenation of steric hindrance enones catalyzed by Ru complexes with chiral diamine and achiral phosphane

Chen, Xiangning,Zhou, Han,Zhang, Kunyu,Li, Jiawen,Huang, Hanmin

, p. 3912 - 3915 (2014/08/18)

An asymmetric hydrogenation of sterically hindered β,β- disubstituted enones has been well-established by using a ruthenium complex composed of an achiral diphosphane and a chiral diamine as catalyst, wherein the carbonyl group was selectively hydrogenated to give a wide range of chiral allylic alcohols with high levels of enantioselectivity and complete chemoselectivity.
