Check Digit Verification of cas no

The CAS Registry Mumber 1208978-02-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,8,9,7 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1208978-02:
(9*1)+(8*2)+(7*0)+(6*8)+(5*9)+(4*7)+(3*8)+(2*0)+(1*2)=172
172 % 10 = 2
So 1208978-02-2 is a valid CAS Registry Number.

Synthesis of spiro(cyclohexa-diene-pyrazolo[1,5-a]pyrimidine-4-ylidene)- malononitrile derivatives

Ibrahim, Yusria R.

, p. 495 - 498 (2009)

The reaction of 4-substituted aryldiazenyl-1H-pyrazole-3,5-diamines with 7,7',8,8'-tetra-cyanoquinodimethane gave 2-(2',7'-diamino-6'-cyano-3'- (aryldiazenyl)-4'H-spiro(cyclohexa[2,5]-diene-1,5'-pyrazolo[1,5-a] pyrimidine-4-ylidene) malononitriles in 63-7
