Check Digit Verification of cas no

The CAS Registry Mumber 864516-20-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,4,5,1 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 864516-20:
(8*8)+(7*6)+(6*4)+(5*5)+(4*1)+(3*6)+(2*2)+(1*0)=181
181 % 10 = 1
So 864516-20-1 is a valid CAS Registry Number.

Ni(II) Tol-BINAP-catalyzed enantioselective Michael reactions of β-ketoesters and unsaturated N-acylthiazolidinethiones

Evans, David A.,Thomson, Regan J.,Franco, Francisco

, p. 10816 - 10817 (2007/10/03)

The enantioselective addition of β-ketoesters to unsaturated N-acylthiazolidinethiones catalyzed by Ni(II) Tol-BINAP Lewis acid complexes is reported. Notable features of this reaction are its operation simplicity, the obviated need for the addition of an
