Check Digit Verification of cas no

The CAS Registry Mumber 1027570-33-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,5,7 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1027570-33:
(9*1)+(8*0)+(7*2)+(6*7)+(5*5)+(4*7)+(3*0)+(2*3)+(1*3)=127
127 % 10 = 7
So 1027570-33-7 is a valid CAS Registry Number.

Catalytic enantioselective conjugate reduction of lactones and lactams

Hughes, Gregory,Kimura, Masanari,Buchwald, Stephen L.

, p. 11253 - 11258 (2007/10/03)

A dramatic acceleration of the enantioselective copper-catalyzed conjugate reduction of α,β-unsaturated lactones, lactams, and esters is reported upon addition of alcohol additives. Good to excellent yields and enantioselectivities were realized using a catalyst generated in situ from CuCl2·H2O, t-BuONa, p-tol-BINAP, and PMHS, and this methodology was applied to the synthesis of (-)-Paroxetine.
