Check Digit Verification of cas no

The CAS Registry Mumber 265643-06-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,5,6,4 and 3 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 265643-06:
(8*2)+(7*6)+(6*5)+(5*6)+(4*4)+(3*3)+(2*0)+(1*6)=149
149 % 10 = 9
So 265643-06-9 is a valid CAS Registry Number.

Opposite π-face selectivity for the DMD and m-CPBA epoxidations of chiral 2,2-dimethyloxazolidine derivatives of tiglic amides: Control by steric interactions versus hydrogen bonding

Adam, Waldemar,Pastor, Aurelia,Peters, Karl,Peters, Eva-Maria

, p. 1019 - 1022 (2007/10/03)

A high extent but opposite sense in the diastereoselectivity has been observed for the DMD and m-CPBA epoxidations of the optically active tiglic amides (S)-1 with 2,2-dimethyloxazolidines as chiral auxiliaries. This unprecedented reversed π-facial differ
