Check Digit Verification of cas no
The CAS Registry Mumber 132746-47-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,7,4 and 6 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 132746-47:
(8*1)+(7*3)+(6*2)+(5*7)+(4*4)+(3*6)+(2*4)+(1*7)=125
125 % 10 = 5
So 132746-47-5 is a valid CAS Registry Number.

New stereospecific syntheses and x-ray diffraction structures of (-)-D-erythro- And (+)-L-threo-4-fluoroglutamic acid
Hudlicky, Milos,Merola, Joseph S.
, p. 7403 - 7406 (1990)
Stereospecific syntheses of (+)-L-threo and (-)-D-erythro-4-fluoroglutamic acid are based on the hydrolysis of methyl 1-acetyl-4-fluoro-L-pyrrolidin-5-one-2-carboxylate, prepared from trans- and cis-4-hydroxyprolines, respectively.
