Check Digit Verification of cas no

The CAS Registry Mumber 74397-08-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,3,9 and 7 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 74397-08:
(7*7)+(6*4)+(5*3)+(4*9)+(3*7)+(2*0)+(1*8)=153
153 % 10 = 3
So 74397-08-3 is a valid CAS Registry Number.

Thiohydrazides and Acetylene Esters, A New Route to 1,3,4-Thiadiazoles

Heindel, Ned D.,Friedrich, Gail,Tsai, Maria C.

, p. 191 - 193 (2007/10/02)

Aromatic thiohydrazides react with dimethyl acetylenedicarboxylate or methyl propiolate to yield carbomethoxymethyl-substituted 1,3,4-thiadiazoles.In a 2:1 ratio of methyl propiolate to aromatic thiohydrazide, 1,3,4-thiadiazoles with acrylate ester side chains are formed.
