Check Digit Verification of cas no

The CAS Registry Mumber 81490-56-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,4,9 and 0 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 81490-56:
(7*8)+(6*1)+(5*4)+(4*9)+(3*0)+(2*5)+(1*6)=134
134 % 10 = 4
So 81490-56-4 is a valid CAS Registry Number.

An Unusual Decarboxylative Aza-cleavage in the Reactions of Azo-coupled β-Arylglutaconic Anhydrides with Amines

Kanekar, D. S.,Samant, S. D.,Pednekar, S. R.,Deval, S. D.,Deodhar, K. D.

, p. 998 - 999 (2007/10/02)

Azo-coupled β-arylglutaconic anhydrides (II) undergo an unusual decarboxylative aza-cleavage on reaction with cyclic secondary amines giving (Z)-3-aryl-3-cyanopropenoic acid amides (IX, X).A plausible mechanism has been suggested.
