Check Digit Verification of cas no

The CAS Registry Mumber 43160-78-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,3,1,6 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 43160-78:
(7*4)+(6*3)+(5*1)+(4*6)+(3*0)+(2*7)+(1*8)=97
97 % 10 = 7
So 43160-78-7 is a valid CAS Registry Number.

IBX/n-Bu4NBr/CH2Cl2-H2O: A new mild system for selective oxidation of secondary alcohols

Kuhakarn, Chutima,Kittigowittana, Krisada,Pohmakotr, Manat,Reutrakul, Vichai

, p. 8995 - 9000 (2007/10/03)

A new alternative system for the chemoselective oxidation of secondary hydroxyl group to ketone with IBX/n-Bu4NBr in CH2Cl 2-H2O has been developed. Under the reaction conditions, the secondary hydroxyl group was highly chemoselectively oxidized to the corresponding ketone, in moderate to good yields at rt, in the presence of primary hydroxyl group within the same molecule.
