Check Digit Verification of cas no

The CAS Registry Mumber 79204-46-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,2,0 and 4 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 79204-46:
(7*7)+(6*9)+(5*2)+(4*0)+(3*4)+(2*4)+(1*6)=139
139 % 10 = 9
So 79204-46-9 is a valid CAS Registry Number.

Reinvestigation of the reaction of trichloroacetyl chloride and acrylonitrile in the preparation of 3,5,6-trichloropyridin-2-ol

Fakhraian,Moghimi,Bazaz,Hadj-Ghanbary,Sadeghi

, p. 329 - 333 (2003)

The synthesis of 3,5,6-trichloropyridin-2-ol via the CuCl-catalyzed reaction of trichloroacetyl chloride and acrylonitrile under both pressure and atmospheric conditions and the hydrolysis of the reaction mixture were reinvestigated. The products and byproducts formed in each case, before the hydrolysis step, were characterized, and the factors causing their formation are discussed. It was found that two newly identified byproducts influence the yield of the reaction.
