Check Digit Verification of cas no
The CAS Registry Mumber 150783-50-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,0,7,8 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 150783-50:
(8*1)+(7*5)+(6*0)+(5*7)+(4*8)+(3*3)+(2*5)+(1*0)=129
129 % 10 = 9
So 150783-50-9 is a valid CAS Registry Number.

Improved Process for the Preparation of 2-Methyl-3-trifluoromethylaniline: A Versatile Intermediate for Flunixin Synthesis
Jaouhari, Rabih,Quinn, Philip
, p. 2243 - 2246 (1994)
A detailed new experimental investigation into the synthesis of Flunixin via 2-methyl-3-trifluoromethylaniline is described.The coupling process between 2-methyl-3-trifluoromethylaniline and 2-chloronicotinate was achieved stoichiometrically and in high yield, when ethylene glycol was used as reaction solvent at 160 deg C.
