Check Digit Verification of cas no

The CAS Registry Mumber 216663-58-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,6,6,6 and 3 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 216663-58:
(8*2)+(7*1)+(6*6)+(5*6)+(4*6)+(3*3)+(2*5)+(1*8)=140
140 % 10 = 0
So 216663-58-0 is a valid CAS Registry Number.

Practical synthesis of tetrasubstituted thiophenes for use in compound libraries

McKibben, Bryan P.,Cartwright, Craig H.,Castelhano, Arlindo L.

, p. 5471 - 5474 (1999)

Tetrasubstituted thiophenes, obtained by optimizing the multi-component reaction originally developed by Gewald, served as key templates for structural diversification and semi-automated library synthesis. Conditions were developed to carry out Gewald's reaction at room temperature and in high yield.
