78790-81-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78790-81-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,7,9 and 0 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 78790-81:
(7*7)+(6*8)+(5*7)+(4*9)+(3*0)+(2*8)+(1*1)=185
185 % 10 = 5
So 78790-81-5 is a valid CAS Registry Number.

Chemoselective Reactions of 3-Chloroisonicotinonitrile
LaMattina, John L.,Taylor, Richard L.
, p. 4179 - 4182 (2007/10/02)
Chemoselective reactions of 3-chloroisonicotinonitrile (1) with nucleophiles are described.Treatment of 1 with sodium methoxide/methanol results in formation of the imino ether, which can be further elaborated into a triazole ring.However, when 1 is react
