Check Digit Verification of cas no

The CAS Registry Mumber 851636-93-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,1,6,3 and 6 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 851636-93:
(8*8)+(7*5)+(6*1)+(5*6)+(4*3)+(3*6)+(2*9)+(1*3)=186
186 % 10 = 6
So 851636-93-6 is a valid CAS Registry Number.

Facile C-N cleavage in a series of bridged lactams

Lei, Yao,Wrobleski, Aaron D.,Golden, Jennifer E.,Powell, Douglas R.,Aube, Jeffrey

, p. 4552 - 4553 (2005)

A series of strained bi- and tricyclic amides has been shown to be unusually sensitive to cleavage of the C-N bond adjacent to the amide moiety. This bond undergoes facile breaking when subjected to treatment with H2/Pd(OH)2, MeI, and DDQ. In each case, the reaction is highly regioselective and mainly results in breaking the C-N bond that deviates the farthest from its natural planar state. Preliminary experiments that bear on the mechanisms of these reactions are described. Copyright
