Check Digit Verification of cas no

The CAS Registry Mumber 4541-96-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,4 and 1 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4541-96:
(6*4)+(5*5)+(4*4)+(3*1)+(2*9)+(1*6)=92
92 % 10 = 2
So 4541-96-2 is a valid CAS Registry Number.

Reactions of α,β-Unsaturated Carboxylates, Malonates and Phenylacetates with Manganese(III) Acetate in the Presence of Chloride Ions

Yonemura, Hiroshi,Nishino, Hiroshi,Kurosawa, Kazu

, p. 809 - 811 (1987)

The reaction of alkyl (E)-3-phenylpropenoates with manganese(III) acetate of Cl- ions gave alkyl (Z)-2-chloro-3-phenylpropenoates and alkyl 2,3-dichloro-3-phenylpropenoates.Ethyl (E)-2,3-diphenylpropenoate yielded ethyl 2,3-dichloro-2,3-diphenylpropanoate.Alkyl 3,3-diphenylpropenoates gave mainly alkyl 2-chloro-3,3-diphenylpropenoates.Ethyl 1-cyclohexenecarboxylate gave ethyl 1,2-dichlorocyclohexanecarboxylate.Dimethyl malonate yielded dimethyl dichloromalonate and tetramethyl 1,2-dichloro-1,1,2,2-ethanetetracarboxylate.Substituted malonates resulted in α-chloro derivatives.Methyl phenylacetates gave α-acetoxy derivatives.
