Check Digit Verification of cas no

The CAS Registry Mumber 77643-09-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,6,4 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 77643-09:
(7*7)+(6*7)+(5*6)+(4*4)+(3*3)+(2*0)+(1*9)=155
155 % 10 = 5
So 77643-09-5 is a valid CAS Registry Number.

THIOSEMICARBAZONES OF 7-AZAISATIN DERIVATIVES

Styngach, E. P.,Azimov, V. A.,Zhungietu, G. I.,Yakhontov, L. N.

, p. 43 - 45 (1981)

A number of derivatives of 7-azaisatin with various substituents in the pyridine and pyrrole rings were synthesized by oxidation of the corresponding 7-azaindoles with chromic acid in acetic acid. 4-Azaindole is not ixidized to 4-azaisatin under these con
