Check Digit Verification of cas no

The CAS Registry Mumber 1039623-41-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,9,6,2 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1039623-41:
(9*1)+(8*0)+(7*3)+(6*9)+(5*6)+(4*2)+(3*3)+(2*4)+(1*1)=140
140 % 10 = 0
So 1039623-41-0 is a valid CAS Registry Number.

Structural optimization of enantiopure 2-cyclialkylamino-2-aryl-1,1- diphenylethanols as catalytic ligands for enantioselective additions to aldehydes

(Chemical Equation Presented) The structural optimization of a family of modular, enantiopure β-amino alcohol ligands with a common 2-amino-2-aryl-1,1-diphenylethanol skeleton, whose stereogenicity was introduced through the Jacobsen epoxidation of 1,1-diphenyl-2-arylethylenes, has led to the identification of a small set of optimal catalysts with enhanced activity and enantioselectivity in the addition of alkylzinc and arylzinc reagents to aldehydes. Criteria for the discrimination between apparently analogous, highly enantioselective ligands are proposed.
