Check Digit Verification of cas no

The CAS Registry Mumber 26775-57-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,7,7 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 26775-57:
(7*2)+(6*6)+(5*7)+(4*7)+(3*5)+(2*5)+(1*7)=145
145 % 10 = 5
So 26775-57-5 is a valid CAS Registry Number.

Boddaert, Thomas,Coquerel, Yoann,Rodriguez, Jean

supporting information; experimental part, p. 2266 - 2271 (2011/03/22)

A study of the organocatalytic activity of N-heterocyclic carbenes (NHCs) in the Michael addition of 1,3-dicarbonyl compounds has allowed us to identify 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene (IPr) as an excellent catalyst for this transformatio
