Calculate Digit Verification of CAS Registry Number 1339950-17:
(9*1)+(8*3)+(7*3)+(6*9)+(5*9)+(4*5)+(3*0)+(2*1)+(1*7)=182
182 % 10 = 2
So 1339950-17-2 is a valid CAS Registry Number.

A stereoselective route to cis-(2S,3R)-3-hydroxypipecolic acid and two enantiomeric cis-2-hydroxymethyl-3-hydroxypiperidine derivatives

Chattopadhyay, Shital K.,Roy, Shankar P.,Saha, Tapan

experimental part, p. 2664 - 2670 (2011/10/04)

Stereoselective routes to cis-(2S,3R)-3-hydroxypipecolic acid and two enantiomeric cis-2-hydroxymethyl-3-hydroxypiperidine derivatives from a common precursor have been developed, which featured stereocontrolled vinylation of a -chiral aldehyde and ring-closing metathesis as key steps.
