Check Digit Verification of cas no

The CAS Registry Mumber 33809-96-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,8,0 and 9 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 33809-96:
(7*3)+(6*3)+(5*8)+(4*0)+(3*9)+(2*9)+(1*6)=130
130 % 10 = 0
So 33809-96-0 is a valid CAS Registry Number.

Catalytic asymmetric cross-couplings of racemic α-bromoketones with arylzinc reagents

Lundin, Pamela M.,Esquivias, Jorge,Fu, Gregory C.

supporting information; experimental part, p. 154 - 156 (2009/04/07)

(Chemical Equation Presented) Nickel box: The first catalytic asymmetric method for cross-coupling arylzinc reagents with α-bromoketones has been developed (see scheme). This stereoconvergent carbon-carbon bond-forming process occurs under unusually mild conditions and without activators, thereby allowing the generation of potentially labile tertiary stereocenters.
