Check Digit Verification of cas no

The CAS Registry Mumber 82202-35-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,2,0 and 2 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 82202-35:
(7*8)+(6*2)+(5*2)+(4*0)+(3*2)+(2*3)+(1*5)=95
95 % 10 = 5
So 82202-35-5 is a valid CAS Registry Number.

Formation of N-Substituted Trichloroacetamides from Amines and Hexachloroacetone

Bew, Clive,Joshi, Virginia Otero de,Gray, Jim,Kaye, Perry T.,Meakins, G. Denis

, p. 945 - 948 (2007/10/02)

Procedures are described for converting primary amines into their well-crystalline trichloroacetyl-derivatives by treatment with hexachloroacetone under mild conditions.Although secondary aromatic N-methylamines are unaffected by hexachloroacetone, saturated heterocyclic amines react vigorously.A mechanistic study using 2-amino-4-t-butylthiazole showed that the reaction is first order in hexachloroacetone, second order in amine, and base-catalysed; there is no appreciable kinetic isotope (H/D) effect nor accumulation of intermediates during the reaction.A sequence which accommodates these results is suggested.
