Check Digit Verification of cas no

The CAS Registry Mumber 420108-08-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,0,1,0 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 420108-08:
(8*4)+(7*2)+(6*0)+(5*1)+(4*0)+(3*8)+(2*0)+(1*8)=83
83 % 10 = 3
So 420108-08-3 is a valid CAS Registry Number.

Dynamic kinetic resolution via asymmetric conjugate reduction: Enantio- and diastereoselective synthesis of 2,4-dialkyl cyclopentanones

Jurkauskas, Valdas,Buchwald, Stephen L.

, p. 2892 - 2893 (2007/10/03)

Herein, we report the kinetic and the dynamic kinetic resolutions of racemic 3,5-dialkyl-2-cyclopenten-1-ones. Kinetic resolution, with good selectivity factors (25-52), was achieved by conjugate reduction with catalytic CuCl/NaOt-Bu/(S)-p-tol-BINAP and s
