Check Digit Verification of cas no

The CAS Registry Mumber 283610-08-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,3,6,1 and 0 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 283610-08:
(8*2)+(7*8)+(6*3)+(5*6)+(4*1)+(3*0)+(2*0)+(1*8)=132
132 % 10 = 2
So 283610-08-2 is a valid CAS Registry Number.

A simple stereoselective synthesis of enantiopure 2-substituted pyrrolidines and piperidines from chiral (R)-phenylglycinol-derived bicyclic 1,3-oxazolidines

Andres, Jose M.,Herraiz-Sierra, Ignacio,Pedrosa, Rafael,Perez-Encabo, Alfonso

, p. 1719 - 1726 (2007/10/03)

Chiral, nonracemic 2-substituted pyrrolidines and piperidines were prepared in high ee and moderate to good chemical yields in three steps from (R)-phenylglycinol and γ- or δ-chloroketones. The key step of the synthesis was the stereo- selective reductive ring-opening of chiral bicyclic 1,3- oxazolidines prepared by condensation of (R)-phenylglycinol and the corresponding ketones.
