Check Digit Verification of cas no

The CAS Registry Mumber 89840-43-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,8,4 and 0 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 89840-43:
(7*8)+(6*9)+(5*8)+(4*4)+(3*0)+(2*4)+(1*3)=177
177 % 10 = 7
So 89840-43-7 is a valid CAS Registry Number.

An Examination of the Extent of Diastereofacial Selection in the Reactions of a Chiral Nitrile Oxide with Achiral Alkenes: a Route to β-Hydroxy Carboxylic Acids

Kozikowski, Alan P.,Kitagawa, Yoshinori,Springer, James P.

, p. 1460 - 1462 (2007/10/02)

A new synthesis of optically active β-hydroxy carboxylic acids has been developed which is based on the (modest) diastereoselective addition of the chiral nitrile oxide (4) to 1,2-disubstituted alkenes.
