Check Digit Verification of cas no

The CAS Registry Mumber 459867-22-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,9,8,6 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 459867-22:
(8*4)+(7*5)+(6*9)+(5*8)+(4*6)+(3*7)+(2*2)+(1*2)=212
212 % 10 = 2
So 459867-22-2 is a valid CAS Registry Number.

Effect of ligand structure on the zinc-catalyzed Henry reaction. Asymmetric syntheses of (-)-denopamine and (-)-arbutamine

Trost, Barry M.,Yeh, Vince S. C.,Ito, Hisanako,Bremeyer, Nadine

, p. 2621 - 2623 (2007/10/03)

(Matrix presented) Syntheses of variously modified ligands for the dinuclear zinc catalysts for the asymmetric aldol and nitroaldol (Henry) reactions are reported. Catalytic enantioselective nitroaldol reactions promoted by these modified ligands led to efficient syntheses of the β-preceptor agonists (-)-denopamine and (-)-arbutamine.
