83505-97-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83505-97-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,5,0 and 5 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 83505-97:
(7*8)+(6*3)+(5*5)+(4*0)+(3*5)+(2*9)+(1*7)=139
139 % 10 = 9
So 83505-97-9 is a valid CAS Registry Number.

Synthesis of Some Alkyl- and Arylimidazoles
Watanabe, T.,Nishiyama, J.,Hirate, R.,Uehara, K.,Inoue, M.,et al.
, p. 1277 - 1281 (2007/10/02)
The pyrolysis of 2-azidopyrazines led to give 1-cyanoimidazoles, which were hydrolyzed in alkaline and acidic media to the corresponding imidazoles.This ring transformation occured also by photolysis.
