Check Digit Verification of cas no

The CAS Registry Mumber 123299-71-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,2,9 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 123299-71:
(8*1)+(7*2)+(6*3)+(5*2)+(4*9)+(3*9)+(2*7)+(1*1)=128
128 % 10 = 8
So 123299-71-8 is a valid CAS Registry Number.

Zinc(ii)-catalyzed Grignard additions to ketones with RMgBr and RMgI

Hatano, Manabu,Ito, Orie,Suzuki, Shinji,Ishihara, Kazuaki

supporting information; experimental part, p. 2674 - 2676 (2010/07/08)

Highly efficient alkylations and arylations of ketones with Grignard reagents (RMgBr and RMgI) have been developed using catalytic ZnCl2, Me3SiCH2MgCl, and LiCl. Tertiary alcohols were obtained in high yields with high chemoselectivities, while minimizing undesired side products produced by reduction and enolization.
