Check Digit Verification of cas no
The CAS Registry Mumber 4668-38-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,6 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4668-38:
(6*4)+(5*6)+(4*6)+(3*8)+(2*3)+(1*8)=116
116 % 10 = 6
So 4668-38-6 is a valid CAS Registry Number.

Chemo-enzymatic preparation of chiral 3-aminopyrrolidine derivatives
Iding, Hans,Wirz, Beat,Rogers-Evans, Mark
, p. 647 - 653 (2007/10/03)
A new simple method for the enantioselective enzymatic hydrolysis of N-protected D-asparagine esters suitable for the use on the preparative scale is presented. Due to major obstacles observed under conventional reaction conditions - racemization of the retained ester and a strong enzyme inactivation - a comparatively low pH together with an organic co-solvent had to be employed. Under these conditions, nearly all tested proteases demonstrated good activity and excellent enantioselectivity giving access to the corresponding D-esters and L-asparagines in high optical purities (>95% ee) and good chemical yields (>40%). From the unnatural D-asparagine derivative, sequential cyclization, selective deprotection and reduction yielded efficiently benzyl protected (R)-3-aminopyrrolidine, a homo-chiral building block utilized in numerous drug candidates.
