Check Digit Verification of cas no

The CAS Registry Mumber 202276-25-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,2,2,7 and 6 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 202276-25:
(8*2)+(7*0)+(6*2)+(5*2)+(4*7)+(3*6)+(2*2)+(1*5)=93
93 % 10 = 3
So 202276-25-3 is a valid CAS Registry Number.

Rotational features of carbon-nitrogen bonds in axially chiral o-tert- butyl anilides and related molecules. Potential substrates for the 'prochiral auxiliary' approach to asymmetric synthesis

Curran, Dennis P.,Hale, Gregory R.,Geib, Steven J.,Balog, Aaron,Cass, Quezia B.,Degani, Ana Luiza G.,Hernandes, Marcelo Z.,Freitas, Luiz Carlos G.

, p. 3955 - 3975 (2007/10/03)

A new strategy for asymmetric induction termed the 'prochiral auxiliary' approach is introduced. Reactions of acylating agents with prochiral N- methyl-o-tert-butyl aniline provide anilides that are axially chiral by virtue of restricted rotation about th
