Check Digit Verification of cas no
The CAS Registry Mumber 816-21-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,1 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 816-21:
(5*8)+(4*1)+(3*6)+(2*2)+(1*1)=67
67 % 10 = 7
So 816-21-7 is a valid CAS Registry Number.

Formation of α-iminoketones and α-diimines versus Favorskii rearrangement products from the reaction of α,α′-dibromoketones and primary amines
De Kimpe, Norbert,D'Hondt, Luc,Mones, Luc
, p. 3183 - 3208 (2007/10/02)
The reaction of aliphatic acyclic α,α'-dibromoketones with primary amines gave rise to α-iminoketones and α-diimines. Both reaction products could be selectively obtained under appropriate reaction conditions. Sterically hindered α,α-dibromoketones did no
