51944-16-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 51944-16-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,9,4 and 4 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 51944-16:
(7*5)+(6*1)+(5*9)+(4*4)+(3*4)+(2*1)+(1*6)=122
122 % 10 = 2
So 51944-16-2 is a valid CAS Registry Number.

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
