Check Digit Verification of cas no

The CAS Registry Mumber 67935-24-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,9,3 and 5 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 67935-24:
(7*6)+(6*7)+(5*9)+(4*3)+(3*5)+(2*2)+(1*4)=164
164 % 10 = 4
So 67935-24-4 is a valid CAS Registry Number.

Iridium-catalyzed asymmetric hydrogenation of vinyl ethers

Zhu, Ye,Burgess, Kevin

supporting information; experimental part, p. 979 - 983 (2009/05/30)

A carbene-oxazoline catalyst 1 proved to be an effective catalyst for reduction of an enol ether that the literature suggested could not be hydrogenated effectively by P,N-Ir catalysts. Thus, a series of ester and alcohol substrates were hydrogenated using catalyst 1. Good to excellent enantioselectivities and high conversions were obtained.
