Check Digit Verification of cas no

The CAS Registry Mumber 289716-59-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,7,1 and 6 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 289716-59:
(8*2)+(7*8)+(6*9)+(5*7)+(4*1)+(3*6)+(2*5)+(1*9)=202
202 % 10 = 2
So 289716-59-2 is a valid CAS Registry Number.

Enantioselective synthesis of α,α'-disubstituted piperidines via ruthenium-catalyzed ring rearrangement

Voigtmann, Ulrike,Blechert, Siegfried

, p. 893 - 898 (2007/10/03)

A new method for the enantioselective synthesis of α,α'-disubstituted piperidines is described. Easily available cyclopentenones 5a,b rearrange via Ru-catalyzed RCM-ROM to heterocycles. Compound 6a is converted to the indolizidine 13.
