Check Digit Verification of cas no

The CAS Registry Mumber 1240326-15-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,3,2 and 6 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1240326-15:
(9*1)+(8*2)+(7*4)+(6*0)+(5*3)+(4*2)+(3*6)+(2*1)+(1*5)=101
101 % 10 = 1
So 1240326-15-1 is a valid CAS Registry Number.

Asymmetric michael addition of aromatic ketones to nitroolefins catalyzed by simple chiral bifunctional primary amine-thioureas

Wang, Liangliang,Xu, Xiaoying,Huang, Jun,Peng, Lin,Huang, Qingchun,Wang, Lixin

experimental part, p. 367 - 372 (2011/03/23)

Simple chiral primary amine-thiourea catalysts derived from chiral 1,2-diphenylethylenediamine were found to catalyze direct Michael addition of aromatic ketones to nitroolefins with good enantioselectives (up to 86% ee) and excellent yields (up to 97%) f
