Check Digit Verification of cas no

The CAS Registry Mumber 221035-77-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,0,3 and 5 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 221035-77:
(8*2)+(7*2)+(6*1)+(5*0)+(4*3)+(3*5)+(2*7)+(1*7)=84
84 % 10 = 4
So 221035-77-4 is a valid CAS Registry Number.

Design and synthesis of a s-triazene based asymmetric organocatalyst and its application in enantioselective alkylation

Mangawa, Shrawan K.,Singh, Ashawani K.,Awasthi, Satish K.

, p. 61144 - 61147 (2015/08/03)

A very efficient chiral organocatalyst was prepared from the readily available cyanuric chloride. The asymmetric catalyst exhibited a highly enantioselective catalytic performance for the alkylation of a glycinate Schiff base, which provides a useful procedure for the enantioselective synthesis of structurally diverse natural and unnatural α-alkyl-α-amino acids.
