Check Digit Verification of cas no

The CAS Registry Mumber 180903-13-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,9,0 and 3 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 180903-13:
(8*1)+(7*8)+(6*0)+(5*9)+(4*0)+(3*3)+(2*1)+(1*3)=123
123 % 10 = 3
So 180903-13-3 is a valid CAS Registry Number.

One-pot synthesis of tetrasubstituted pyrazoles - Proof of regiochemistry

Hanefeld, Ulf,Rees, Charles W.,White, Andrew J. P.,Williams, David J.

, p. 1545 - 1552 (2007/10/03)

1-Alkyl-5-amino-3-aryl-4-cyanopyrazoles, useful intermediates for fused heterocyclic systems, are synthesised by a one-pot three-step procedure from acid chlorides, malononitrile and alkylhydrazines. The regiochemistry of the hydrazine incorporation was p
