Check Digit Verification of cas no

The CAS Registry Mumber 1727-36-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,2 and 7 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1727-36:
(6*1)+(5*7)+(4*2)+(3*7)+(2*3)+(1*6)=82
82 % 10 = 2
So 1727-36-2 is a valid CAS Registry Number.

Alkylations of Trichloromethylketones Effected by Trichloroacetate and a Complex Consecutive Reaction

Dehmlow, Eckehard V.,Raths, Hans-Christian

, p. 918 - 920 (2007/10/02)

A phase transfer reaction between the title ketones, sodium trichloroacetate, and an alkyl halide leads to 2a, b, 4, or 5.Whereas these compounds are fragmented by NaOH, sodium methoxide/methylmalonate/methanol give compound 8 from 5 in a complex series of consecutive rearrangements. - Key words: Trichloromethylketones, Phase Transfer Reaction
