Check Digit Verification of cas no

The CAS Registry Mumber 1629211-99-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,9,2,1 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1629211-99:
(9*1)+(8*6)+(7*2)+(6*9)+(5*2)+(4*1)+(3*1)+(2*9)+(1*9)=169
169 % 10 = 9
So 1629211-99-9 is a valid CAS Registry Number.

Enantioselective organocatalytic conjugate addition of alkenes to α,β-enones

Cui, Lingyun,Zhang, Long,Luo, Sanzhong,Cheng, Jin-Pei

supporting information, p. 3540 - 3545 (2014/06/23)

We report the first example of the enantioselective conjugate addition of alkenes (aromatic enamines) to enones catalyzed by chiral primary amines. The reactions encompass a plethora of α,β-enones including difficult α-substituted vinyl ketones to give vinylation adducts in high yields with good enantioselectivity. The methodology is of synthetic potential in accessing chiral functional materials. Copyright
