Check Digit Verification of cas no

The CAS Registry Mumber 196491-79-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,6,4,9 and 1 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 196491-79:
(8*1)+(7*9)+(6*6)+(5*4)+(4*9)+(3*1)+(2*7)+(1*9)=189
189 % 10 = 9
So 196491-79-9 is a valid CAS Registry Number.

Desymmetrization of prochiral anhydrides with Evans' oxazolidinones: An efficient route to homochiral glutaric and adipic acid derivatives

Verma, Rekha,Mithran, Seturam,Ghosh, Sunil K.

, p. 257 - 264 (2007/10/03)

The prochiral recognition between enantiotopic carbonyl groups in the reaction of 3-substituted glutaric and 3,4-disubstituted adipic anhydrides with anions of Evans' oxazolidinones has been investigated. Each of the σ-symmetric anhydrides provided a diastereoisomeric mixture of half-acids which were separated either by fractional crystallization or by column chromatography of their esters. The diastereoselectivity of the desymmetrization reaction is dependent on the substituents present in the anhydrides.

A silicon controlled total synthesis of the antifungal agent (+)-preussin

Verma, Rekha,Ghosh, Sunil K.

, p. 1601 - 1602 (2007/10/03)

A stereoselective total synthesis of (+)-preussin has been achieved from a meso anhydride featuring a dimethyl(phenyl)silyl group as a masked hydroxy group which also restricts elimination reactions, stereodirects hydrogenation and ester enolate alkylation, and facilitates Curtius reaction.
