Check Digit Verification of cas no

The CAS Registry Mumber 23040-02-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,0,4 and 0 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 23040-02:
(7*2)+(6*3)+(5*0)+(4*4)+(3*0)+(2*0)+(1*2)=50
50 % 10 = 0
So 23040-02-0 is a valid CAS Registry Number.

Asymmetric hydrogenation of enol phosphinates by iridium catalysts having N,P ligands

Cheruku, Pradeep,Gohil, Suresh,Andersson, Pher G.

, p. 1659 - 1661 (2008/02/02)

Enol phosphinates, which are structural analogues of enol acetates, have for the first time been employed as substrates for Ir-catalyzed asymmetric hydrogenation. A number of enol phosphinates have been synthesized and reduced successfully with up to and above 99% ee.
