759-71-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 759-71-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,5 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 759-71:
(5*7)+(4*5)+(3*9)+(2*7)+(1*1)=97
97 % 10 = 7
So 759-71-7 is a valid CAS Registry Number.

FORMATION DE CETONES ETHYLENIQUES PAR ACTION D'ACIDE ACETYLSULFOACETIQUE SUR DES ALCENES

Loiseau, Andre-Michel,Luft, Robert,Zunino, Serge

, p. 144 - 152 (2007/10/02)

Monoalkyl- and 1,2-dialkylethylenes have a similar behaviour under the action of acetylsulfoacetic acid : the reaction does not necessarily stop after the formation of α- or β-enones, the yield of which is highly influenced by reaction time; thus, 1-acetoxy-1,3-dienes are identified in the case of α-enones.A different behaviour is shown by 1,1-dialkyl and trialkylethylenes, which can constitute an interesting source of highly branched enones.With this second group of alkenes, isomerisation of the alkene is sometimes observed prior to acetylation.Lastly, some alkenes undergo acetoxylation at the same time as acetylation.
