124938-13-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 124938-13-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,9,3 and 8 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 124938-13:
(8*1)+(7*2)+(6*4)+(5*9)+(4*3)+(3*8)+(2*1)+(1*3)=132
132 % 10 = 2
So 124938-13-2 is a valid CAS Registry Number.

A NEW ROUTE TO OPTICALLY PURE cis- AND trans-2,5-DISUBSTITUTED PYRROLIDINES
Jegham, Samir,Das, Bhupesh C.
, p. 2801 - 2804 (1989)
A new route to optically pure cis- and trans-2,5-disubstituted pyrrolidines is described and is illustrated by the enantiospecific synthesis of (2R,5S)-(+)-2-ethyl-5-heptylpyrrolidine 9 and (2R,5R)-(-)-2-ethyl-5-heptylpyrrolidine 10 starting from (R)-(-)-2-amino-1-butanol 1.
