Check Digit Verification of cas no

The CAS Registry Mumber 112344-59-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,3,4 and 4 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 112344-59:
(8*1)+(7*1)+(6*2)+(5*3)+(4*4)+(3*4)+(2*5)+(1*9)=89
89 % 10 = 9
So 112344-59-9 is a valid CAS Registry Number.

Stereochemistry of Addition of Allyl Grignard Reagents to (R)-(+)-Pulegone and Other α,β-Ethylenic Ketones

Idrissi, Mostafa El,Santelli, Maurice

, p. 1010 - 1016 (2007/10/02)

The 1,2-addition of allyl, crotyl, and 2-methyl-2-butenyl Grignard reagents to (R)-(+)-pulegone is regio- and stereoselective.In contrast 3-penten-2-yl and 3-methyl-2-butenyl Grignard reagents undergo 1,2- and 1,4-additions.A "compact approach" stabilized by orbital interaction is the proposed mechanism.A further confirmation was obtained with acyclic enones.
