Check Digit Verification of cas no

The CAS Registry Mumber 241818-05-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,1,8,1 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 241818-05:
(8*2)+(7*4)+(6*1)+(5*8)+(4*1)+(3*8)+(2*0)+(1*5)=123
123 % 10 = 3
So 241818-05-3 is a valid CAS Registry Number.

A New Approach to Remote Asymmetric Induction in the Diastereoselective Reduction of γ-Keto Esters by Use of a Chiral Podand as Chiral Auxiliary

Tamai, Yasufumi,Koike, Shinji,Ogura, Atsuhiko,Miyano, Sotaro

, p. 799 - 800 (2007/10/02)

An efficient 1,7-asymmetric induction was achieved with up to 82percent diastereoisomeric excess (d.e.) in the diastereoselective reduction of the γ-keto ester 4 and o-acetylbenzoate 6 using a chiral podand 2 as a chiral auxiliary.
