117101-71-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117101-71-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,1,0 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 117101-71:
(8*1)+(7*1)+(6*7)+(5*1)+(4*0)+(3*1)+(2*7)+(1*1)=80
80 % 10 = 0
So 117101-71-0 is a valid CAS Registry Number.

Synthesis of Substituted Pyrazolo--as-triazines
Heinisch, L.
, p. 57 - 64 (2007/10/02)
Some new substituted pyrazolo--as-triazines (6a-f, 7a-c) were synthesized by cyclisation of pyrazoline-4,5-dion-4-isothiosemicarbazones (5a-c) and -4-amidinohydrazones (4a-f) in phenol at 180-200 deg C. 3-Ethylmercapto-7-phenyl-pyrazolo--as-
