Check Digit Verification of cas no

The CAS Registry Mumber 74128-90-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,1,2 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74128-90:
(7*7)+(6*4)+(5*1)+(4*2)+(3*8)+(2*9)+(1*0)=128
128 % 10 = 8
So 74128-90-8 is a valid CAS Registry Number.

One-Step Conversion of Methyl Ketones to Acyl Chlorides

Zaragoza, Florencio

, p. 10370 - 10374 (2015)

Treatment of aromatic and heteroaromatic methyl ketones with sulfur monochloride and catalytic amounts of pyridine in refluxing chlorobenzene leads to the formation of acyl chlorides. Both electron-rich and electron-poor aryl methyl ketones can be used as starting materials. The resulting C1-byproduct depends on the precise reaction conditions chosen.

Summary - α-Thioxothioamides : [4 + 2] cycloaddition reactions with dimethyl acetylenedicarboxylate and methyl propiolate

Marchand, Evelyne,Morel, Georges

, p. 903 - 912 (2007/10/03)

The title compounds are prepared from methyl ketones through a three-step reaction: chloration with thionyl chloride; amination of the resulting α-chloro-β-oxosulfenyl chlorides; and thionation of α-oxothioamides with Lawesson's reagent. Two competitive h

α-Oxo- and α-Thioxothioamides from Methyl Ketones

Adiwidjaja, Gunadi,Guenther, Horst,Voss, Juergen

, p. 1116 - 1132 (2007/10/02)

Mixtures of α-(chloro)sulfenyl chlorides 5 and trisulfides 6 are obtained from the reaction of thionyl chloride with methyl ketones in the presence of pyridine.From these mixtures as well as from the pure trisulfides 6, with amines the α-oxothioamides 1-4
