Check Digit Verification of cas no

The CAS Registry Mumber 1221065-81-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,1,0,6 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1221065-81:
(9*1)+(8*2)+(7*2)+(6*1)+(5*0)+(4*6)+(3*5)+(2*8)+(1*1)=101
101 % 10 = 1
So 1221065-81-1 is a valid CAS Registry Number.

Enantioselective alkenylation via nickel-catalyzed cross-coupling with organozirconium reagents

Lou, Sha,Fu, Gregory C.

, p. 5010 - 5011 (2010)

A new family of organometallic compounds, organozirconium reagents, are shown to serve as suitable partners in cross-coupling reactions of (activated) secondary alkyl electrophiles. Thus, the first catalytic method for coupling secondary a-bromoketones with alkenylmetal reagents has been developed, specifically, a mild, versatile, and stereoconvergent carbon-carbon bond-forming process that generates potentially labile β,-unsaturated ketones with good enantioselectivity.
