634900-36-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 634900-36-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,4,9,0 and 0 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 634900-36:
(8*6)+(7*3)+(6*4)+(5*9)+(4*0)+(3*0)+(2*3)+(1*6)=150
150 % 10 = 0
So 634900-36-0 is a valid CAS Registry Number.

Synthesis of 1-amino-1,2,4-triazolium 4-nitroimides and their reactions with electrophiles
Glushkov,Shitov,Tartakovsky
, p. 467 - 470 (2003)
A procedure was developed for the preparation of 1-amino-1,2,4-triazolium 4 nitroimides by animation of triethylammonium salts of 4-nitramino-1,2,4- triazoles with O-picrylhydroxylamine. The resulting nitroimides reacted with electrophilic reagents (acyl
