Check Digit Verification of cas no
The CAS Registry Mumber 663193-90-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,3,1,9 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 663193-90:
(8*6)+(7*6)+(6*3)+(5*1)+(4*9)+(3*3)+(2*9)+(1*0)=176
176 % 10 = 6
So 663193-90-6 is a valid CAS Registry Number.

An efficient kinetic resolution of axially chiral 5- or 8-substituted quinoline derivatives was developed through asymmetric transfer hydrogenation of heteroaromatic moiety, simultaneously obtaining two kinds of axially chiral skeletons with up to 209 of selectivity factor. This represents the first successful application of asymmetric transfer hydrogenation of heteroaromatics in kinetic resolution of axially chiral biaryls.
