61997-71-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 61997-71-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,9,9 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 61997-71:
(7*6)+(6*1)+(5*9)+(4*9)+(3*7)+(2*7)+(1*1)=165
165 % 10 = 5
So 61997-71-5 is a valid CAS Registry Number.

Preparation stereoselective de methyle cetones α-bromees: stereochimie de l'addition d'anions en α d'un groupe sulfone sur des cyclohexanones monocycliques et steroidiques

Begue, Jean-Pierre,Bonnet-Delpon, Daniele,Charpentier-Morize, Micheline,Sansoulet, Jean

, p. 2087 - 2092 (2007/10/02)

This work describes stereochemical results obtained for the preparation of α-bromomethyl ketones or α-bromoaldehydes starting from monocyclic and steroid cyclohexanones, using the Durst method.In all the cases studied here, the bromine is introduced selectively in the equatorial position.However, for monocyclic compounds, the yields of α-bromocarbonyl compounds are limited by the competitive formation of α-ethylenic carbonyl compounds.
