Check Digit Verification of cas no

The CAS Registry Mumber 78386-63-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,3,8 and 6 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 78386-63:
(7*7)+(6*8)+(5*3)+(4*8)+(3*6)+(2*6)+(1*3)=177
177 % 10 = 7
So 78386-63-7 is a valid CAS Registry Number.

CYCLOADDITIONS INTRAMOLECULAIRES CATIONIQUE 3+ + 2 ET DIPOLAIRE-1,3 DE PHENYLHYDRAZONES.

Fouchet, B.,Joucla, M.,Hamelin, J.

, p. 1333 - 1336 (1981)

In acidic medium, alkenyl phenylhydrazones lead, probably via a 3+ + 2 cationic cycloaddition, to fused ring system, which are difficult to obtain as primary products of thermal 1,3 dipolar cycloaddition.
