Check Digit Verification of cas no

The CAS Registry Mumber 1239921-76-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,9,2 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1239921-76:
(9*1)+(8*2)+(7*3)+(6*9)+(5*9)+(4*2)+(3*1)+(2*7)+(1*6)=176
176 % 10 = 6
So 1239921-76-6 is a valid CAS Registry Number.

Asymmetric alkyl-alkyl cross-couplings of unactivated secondary alkyl electrophiles: Stereoconvergent suzuki reactions of racemic acylated halohydrins

Owston, Nathan A.,Fu, Gregory C.

supporting information; experimental part, p. 11908 - 11909 (2010/11/04)

A method for asymmetric alkyl-alkyl Suzuki reactions of unactivated secondary alkyl electrophiles, specifically, cross-couplings of racemic acylated halohydrins with alkylborane reagents, has been developed. A range of protected bromohydrins, as well as a protected chlorohydrin and a homologated bromohydrin, are coupled in good ee by a catalyst derived from commercially available components.
