908520-77-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 908520-77-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,8,5,2 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 908520-77:
(8*9)+(7*0)+(6*8)+(5*5)+(4*2)+(3*0)+(2*7)+(1*7)=174
174 % 10 = 4
So 908520-77-4 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
experimental part, 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.
