Check Digit Verification of cas no

The CAS Registry Mumber 263761-80-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,3,7,6 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 263761-80:
(8*2)+(7*6)+(6*3)+(5*7)+(4*6)+(3*1)+(2*8)+(1*0)=154
154 % 10 = 4
So 263761-80-4 is a valid CAS Registry Number.

A convenient route for the synthesis of some new Bi-and triheterocondensed uracils

Abdel-Megid

experimental part, p. 316 - 324 (2011/05/14)

Some bifunctional heterocyclic systems having vicinal chlorocyano, chloroacetyl, and chloro-ethoxycarbonyl groups in their structures reacted with 6-amino-1,3-dimethyluracil to afford novel triheterocyclic systems having a pyrimidinedione moiety. Enaminones and a-cyanocinnamic acid derivatives in this reaction gave pyrido[2,3-d]pyrimidinediones. The antimicrobial activity of some new synthesized triheterocyclic systems was studied. 2010 Springer Science+Business Media, Inc.
