Check Digit Verification of cas no

The CAS Registry Mumber 1372687-90-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,2,6,8 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1372687-90:
(9*1)+(8*3)+(7*7)+(6*2)+(5*6)+(4*8)+(3*7)+(2*9)+(1*0)=195
195 % 10 = 5
So 1372687-90-5 is a valid CAS Registry Number.

Asymmetric michael addition of substituted rhodanines to α,β-unsaturated ketones catalyzed by bulky primary amines

Yu, Feng,Hu, Haoxiang,Gu, Xiaodong,Ye, Jinxing

, p. 2038 - 2041 (2012/07/28)

A bulky group was introduced by design into a diamine catalyst, and a series of robust and tunable bulky chiral primary amine catalysts were developed and successfully applied in the direct conjugate addition of substituted rhodanines to α,β-unsaturated ketones. High yields (up to 99%) and excellent diastereoselectivities (up to 99:1 dr) and enantioselectivities (up to 98% ee) were observed.
