Check Digit Verification of cas no

The CAS Registry Mumber 138943-76-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,9,4 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 138943-76:
(8*1)+(7*3)+(6*8)+(5*9)+(4*4)+(3*3)+(2*7)+(1*6)=167
167 % 10 = 7
So 138943-76-7 is a valid CAS Registry Number.

Interception of an Iminium Ion Equivalent by Intramolecular Nucleophilic Attack by a Silyl Ether during Lithium Aluminium Hydride Reduction of a Tertiary Lactam

Ramsden, Nigel G.,Fleet, George W. J.,Namgoong, Sung Keon

, p. 1991 - 1994 (2007/10/02)

The efficient formation of a bicyclic oxazolidine by lithium aluminium hydride reduction of a tertiary amide provides an example of intramolecular nucleophilic capture of an iminium ion equivalent by the oxygen of a silyl ether.
