Check Digit Verification of cas no

The CAS Registry Mumber 1533400-55-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,3,3,4,0 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1533400-55:
(9*1)+(8*5)+(7*3)+(6*3)+(5*4)+(4*0)+(3*0)+(2*5)+(1*5)=123
123 % 10 = 3
So 1533400-55-3 is a valid CAS Registry Number.

Asymmetric synthesis of N-stereogenic molecules: Diastereoselective double aza-Michael reaction

Lauber, Alex,Zelenay, Benjamin,Cvengros, Jan

supporting information, p. 1195 - 1197 (2014/02/14)

A novel approach towards the asymmetric synthesis of N-stereogenic molecules via double aza-Michael addition was developed. The diastereomeric ratio can be increased by a thermodynamically controlled isomerization mechanism. Simple separation and functionalization of the products afford N-stereogenic compounds in high enantiomeric purity.
