Check Digit Verification of cas no
The CAS Registry Mumber 56554-80-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,5,5 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 56554-80:
(7*5)+(6*6)+(5*5)+(4*5)+(3*4)+(2*8)+(1*0)=144
144 % 10 = 4
So 56554-80-4 is a valid CAS Registry Number.

LIGHT INDUCED HALOGENATIVE DECARBOXYLATION OF THIOHYDROXAMIC ESTERS
Dauben, William G.,Kowalczyk, Bruce A.,Bridon, Dominique P.
, p. 2461 - 2464 (2007/10/02)
The generality of lidht initiated halogenative decarboxylation of thiohydroxamic esters was studied.This method gave high yields of alkyl chlorides, bromides and iodides derived from primary, secondary and tertiairy substituted carboxylic acids.
