Check Digit Verification of cas no
The CAS Registry Mumber 90940-54-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,9,4 and 0 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 90940-54:
(7*9)+(6*0)+(5*9)+(4*4)+(3*0)+(2*5)+(1*4)=138
138 % 10 = 8
So 90940-54-8 is a valid CAS Registry Number.

Ethyl 2,4-dioxo-4-phenylbutyrate: A versatile intermediate for the large-scale preparation of enantiomerically pure α-hydroxy and α-amino acid esters
Blaser, Hans-Ulrich,Burkhardt, Stephan,Kirner, Hans Juerg,Moessner, Tanja,Studer, Martin
, p. 1679 - 1682 (2007/10/03)
Starting from ethyl 2,4-dioxo-4-phenylbutyrate, both enantiomers of six enantiomerically pure α-hydroxy and α-amino acid esters (homophenylalanine derivatives) were prepared on >100 g scale. The key step involves a Pt-cinchona catalyzed enantioselective hydrogenation followed by enrichment via crystallization. All derivatives are commercially available.
