77117-17-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77117-17-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,1 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 77117-17:
(7*7)+(6*7)+(5*1)+(4*1)+(3*7)+(2*1)+(1*7)=130
130 % 10 = 0
So 77117-17-0 is a valid CAS Registry Number.

Rearrangement of 4-Aryl-1,2,4-triazine into the 4-Amino Derivatives
Ibrahim, Yehia A.,Eid, M. M.,Abdel-Hady, S. A. L.

The action of hydrazine on 3-methylmercapto-5-oxo-4-aryl-4,5-dihydro-1,2,4-triazines led to a novel rearrangement and gave 3-arylamino-4-amino-5-oxo-4,5-dihydro-1,2,4-triazines.The mechanism of this rearrangement was discussed.
