Check Digit Verification of cas no

The CAS Registry Mumber 17277-03-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,2,7 and 7 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 17277-03:
(7*1)+(6*7)+(5*2)+(4*7)+(3*7)+(2*0)+(1*3)=111
111 % 10 = 1
So 17277-03-1 is a valid CAS Registry Number.

Solid-phase parallel synthesis of 5-amino- and 5-amido-1,2,4-thiadiazole derivatives via cyclization reactions of a carboxamidine thiourea linker

Ryu, In Ae,Park, Joo Yeon,Han, Hyea Chul,Gong, Young-Dae

experimental part, p. 999 - 1003 (2009/10/10)

A general method is described for the solid-phase parallel synthesis of 5-amino- and 5-amido-l,2,4-thiadiazoles. The sequence developed for this purpose is based on cyclization reactions of resin-bound carboxamidine thioureas promoted by p-toluenesulfonyl
