77202-19-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77202-19-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,2,0 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 77202-19:
(7*7)+(6*7)+(5*2)+(4*0)+(3*2)+(2*1)+(1*9)=118
118 % 10 = 8
So 77202-19-8 is a valid CAS Registry Number.

The Reaction of 1,2,3-Triazines with Grignard Reagents
Ohsawa, Akio,Kaihoh, Terumitsu,Igeta, Hiroshi
, p. 1370 - 1371 (1985)
Monocyclic 1,2,3-triazines reacted with Grignard reagents to form adducts due to N-2 and C-5 attack together with β-substituted acrylaldehydes and N-substituted pyrazoles; the results show that the N-2, C-4, and C-5 positions are reactive towards Grignard reagents.
