Check Digit Verification of cas no
The CAS Registry Mumber 1186694-50-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,6,6,9 and 4 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1186694-50:
(9*1)+(8*1)+(7*8)+(6*6)+(5*6)+(4*9)+(3*4)+(2*5)+(1*0)=197
197 % 10 = 7
So 1186694-50-7 is a valid CAS Registry Number.

Pyrazole-3(5)-diazonium salts in the synthesis of novel pyrazolo[5, 1-c][1, 2, 4]triazines
Shikhaliev,Didenko,Voronkova,Kryl'Skii
scheme or table, p. 1034 - 1040 (2010/10/04)
Coupling of pyrazole-3(5)-diazonium salts with cyclic 1, 3-dicarbonyl (active methylene) compounds followed by cyclocondensation of the resulting hetarylhydrazones gave novel pyrazolo[5, 1-c][1, 2, 4]triazines.
