84679-83-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 84679-83-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,6,7 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 84679-83:
(7*8)+(6*4)+(5*6)+(4*7)+(3*9)+(2*8)+(1*3)=184
184 % 10 = 4
So 84679-83-4 is a valid CAS Registry Number.

Electrochemical Acylation and Carboxylation of Some Activated Olefins

Degrand, Chantal,Mora, Raymond,Lund, Henning

, p. 429 - 436 (2007/10/02)

The electrochemical acylation and carboxylation of some activated olefins have been investigated.Acenaphthylene yields thus on reductive electrochemical acetylation mainly the Z and E enol acetates of 1-(1,2-dihydro-1-acenaphthylidene)ethanone, whereas carboxylation followed by methylation gives trans-1,2-dimethoxycarbonyl-1,2-dihydroacenaphthene.Ethyl cinnamate can be acylated and carboxylated in the 3-position, whereas benzoylacetone could be carboxylated but not acetylated.Neither carboxylation nor acylation were able to compete with the dimerization of benzylidenemalonitrile.Cyclic voltammetry showed that carboxylation generally was faster than acetylation.
