Check Digit Verification of cas no

The CAS Registry Mumber 330583-66-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,0,5,8 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 330583-66:
(8*3)+(7*3)+(6*0)+(5*5)+(4*8)+(3*3)+(2*6)+(1*6)=129
129 % 10 = 9
So 330583-66-9 is a valid CAS Registry Number.

A polymer-supported proline-based diamine catalyst for the kinetic resolution of racemic secondary alcohols

Clapham,Cho,Janda

, p. 868 - 873 (2001)

The preparation of polymer-supported proline-based diamine catalyst 12 for the kinetic resolution of racemic mixtures of secondary alcohols is described. Not only is the catalyst effective for the resolution of a host of different alcohols, it can also be recovered and reused several times without loss of either activity or selectivity. The catalyst has been used in conjunction with a polymer-supported sequestration strategy, giving rise to an essentially pure mixture of resolved products that can be separated using flash chromatography.
