Check Digit Verification of cas no

The CAS Registry Mumber 103722-05-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,7,2 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 103722-05:
(8*1)+(7*0)+(6*3)+(5*7)+(4*2)+(3*2)+(2*0)+(1*5)=80
80 % 10 = 0
So 103722-05-0 is a valid CAS Registry Number.

Oxidative Halo-Decarboxylation of α,β-Unsaturated Carboxylic Acids

Graven, Anette,Joergensen, Karl Anker,Dahl, Soeren,Stanczak, Andrzej

, p. 3543 - 3546 (1994)

A procedure for oxidative halo-decarboxylation of α,β-unsaturated carboxylic acids using iodosylbenzene, or iodosylbenzene diacetate, and N-chloro-, N-bromo-, or N-iodosuccinimide is presented.Good yields of the corresponding bromoalkenes are obtained when the α,β-unsaturated carboxylic acids are substituted with an aromatic substituent in the β-position and N-bromosuccinimide is used as the halogenation reagent.The scope of mainly the oxidative bromo-decarboxylation reaction is presented, and a tentative mechanism is proposed.
