Check Digit Verification of cas no

The CAS Registry Mumber 681244-47-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,1,2,4 and 4 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 681244-47:
(8*6)+(7*8)+(6*1)+(5*2)+(4*4)+(3*4)+(2*4)+(1*7)=163
163 % 10 = 3
So 681244-47-3 is a valid CAS Registry Number.

Method Of Reducing A Functional Group In An Oxidized Form

-

Page/Page column 13, (2008/12/08)

A novel method of reducing a functional group in an oxidised form. The invention relates more particularly to the reduction of aldehyde, ketone, ester, lactone, nitrile or phosphine oxide groups. The reduction method according to the invention is characterised in that it comprises exposing the substrate including the functional group to be reduced to the presence of a siloxane-type compound of the following formula (I), combined with a Lewis acid-type catalyst. In said formula (I):—R1 and R2, which are the same or different, are an alkyl, cycloalkyle or aryl group, —X is a digit from 0 to 50.
