Check Digit Verification of cas no
The CAS Registry Mumber 4083-85-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,8 and 3 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4083-85:
(6*4)+(5*0)+(4*8)+(3*3)+(2*8)+(1*5)=86
86 % 10 = 6
So 4083-85-6 is a valid CAS Registry Number.

Chemo-enzymatic synthesis of specifically stable-isotope labelled L-glutamic acid and 2-oxoglutaric acid
Cappon, J. J.,Baart, J.,Walle, G. A. M. van der,Raap, J.,Lugtenburg, J.
, p. 158 - 166 (2007/10/02)
(3-13C)-(4-13C)-,(5-13C)- and (3,4-13C2)-2-oxoglutaric acid were prepared starting from the simple 13C-enriched compounds: ethyl bromoacetate and paraformaldehyde, via a single reaction scheme on the gram scale in high yield.This reaction scheme allows specific 13C enrichment of every carbon position and any combination of positions. (3-13C)-,(4-13C)-, (5-13C), (3,4-13C2) and (15N)-L-glutamic acid were prepared by converting the corresponding 2-oxoglutaric acids via an enantioselective enzymatic conversion.The labelled L-glutamic acids and 2-oxoglutaric acids were characterized by 1H NMR, 13C NMR and mass spectrometry.
