Check Digit Verification of cas no

The CAS Registry Mumber 1621189-46-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,1,1,8 and 9 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1621189-46:
(9*1)+(8*6)+(7*2)+(6*1)+(5*1)+(4*8)+(3*9)+(2*4)+(1*6)=155
155 % 10 = 5
So 1621189-46-5 is a valid CAS Registry Number.

Synthesis and characterization of new chiral azolinium salts, precursors to N-heterocyclic carbenes, derived from l-proline

Thomasset, Amélia,Bouchardy, Lucie,Bournaud, Chloée,Guillot, Régis,Toffano, Martial,Vo-Thanh, Giang

, p. 242 - 250 (2014/03/21)

A short and flexible procedure for the preparation of seven chiral azolinium and five functionalized chiral azolinium salts, precursors to N-heterocyclic carbenes, derived from l-proline has been developed. Moderate to good overall yields were obtained. Some NHC dimers and thiones were isolated. X-ray crystal structure determinations of two [Rh-NHC] complexes were also reported.
