Check Digit Verification of cas no

The CAS Registry Mumber 1126518-91-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,6,5,1 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1126518-91:
(9*1)+(8*1)+(7*2)+(6*6)+(5*5)+(4*1)+(3*8)+(2*9)+(1*1)=139
139 % 10 = 9
So 1126518-91-9 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.
