Check Digit Verification of cas no

The CAS Registry Mumber 90854-91-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,8,5 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 90854-91:
(7*9)+(6*0)+(5*8)+(4*5)+(3*4)+(2*9)+(1*1)=154
154 % 10 = 4
So 90854-91-4 is a valid CAS Registry Number.

ADDITION REACTIONS WITH 1,3-THIAZOLE-5(4H)-THIONES; SYNTHESIS OF SPIROCYCLIC AND FUSED BICYCLIC SULFUR HETEROCYCLES

Heimgartner, Heinz

, p. 281 - 293 (2007/10/02)

Various 1,6-dithiaspiro heterocycles can be synthesized from 1,3-thiazole-5(4H)-thiones via 1,3-dipolar cycloadditions, Diels-Alder reactions, ring expansion of oxiranes, and C-alkenylation followed by radical cyclization. 1,3-Thiazole-5(4H)-thiones with
