Check Digit Verification of cas no

The CAS Registry Mumber 1254367-11-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,4,3,6 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1254367-11:
(9*1)+(8*2)+(7*5)+(6*4)+(5*3)+(4*6)+(3*7)+(2*1)+(1*1)=147
147 % 10 = 7
So 1254367-11-7 is a valid CAS Registry Number.

Diastereoselective access to trans -2-substituted cyclopentylamines

Joosten, Antoine,Lambert, Emilie,Vasse, Jean-Luc,Szymoniak, Jan

supporting information; experimental part, p. 5128 - 5131 (2011/01/05)

A highly diastereoselective synthesis of trans-2-substituted cyclopentylamines via a tandem hydrozirconation/Lewis acid-mediated cyclization sequence applied to butenyl oxazolidines is described. The method allows an easy preparation of diversely substituted cyclopentylamines which appear to be useful synthetic intermediates. This was further illustrated by the syntheses of (±)-Rodocaine, (±)-trans-pentacin, and enantiomerically enriched trans-cyclopentane-1,2-diamine.
