Check Digit Verification of cas no
The CAS Registry Mumber 871122-28-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,1,1,2 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 871122-28:
(8*8)+(7*7)+(6*1)+(5*1)+(4*2)+(3*2)+(2*2)+(1*8)=150
150 % 10 = 0

Synthesis of phenazone derivatives
Moustafa, Ahmed H.,Saad, Hosam A.
, p. 328 - 331 (2007/10/03)
Some new phenazone (antipyrin) derivatives 2-11 have been synthesised by acylation, alkylation, condensation and ring closure reactions of 4-aminophenazone 1. The structures of the products have been secured by elemental analyses and spectral data (IR, s
