Check Digit Verification of cas no

The CAS Registry Mumber 253275-89-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,3,2,7 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 253275-89:
(8*2)+(7*5)+(6*3)+(5*2)+(4*7)+(3*5)+(2*8)+(1*9)=147
147 % 10 = 7
So 253275-89-7 is a valid CAS Registry Number.

A practical new chiral controller for asymmetric Diels-Alder and alkylation reactions

Sarakinos, Georgios,Corey

, p. 1741 - 1744 (2008/02/11)

(formula presented) The enantiomerically pure hydroxy sulfones (+)- and (-)-2 have been prepared from 1,2-epoxycyclohexane by a simple and practical procedure. The acrylate esters of these alcohols undergo BCl3-catalyzed Diels-Alder reactions with a variety of dienes at -78 to -55°C in CH2Cl2 or C7H8 with high dienophile face selectivity (Table 1). The chiral esters so formed are readily cleaved with recovery of the controllers (+)- or (-)-2. Esters of (+)- and (-)-2 can be converted to Z-polassium enolates and alkylated with high face selectivity.
