Check Digit Verification of cas no
The CAS Registry Mumber 900310-00-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,0,3,1 and 0 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 900310-00:
(8*9)+(7*0)+(6*0)+(5*3)+(4*1)+(3*0)+(2*0)+(1*0)=91
91 % 10 = 1
So 900310-00-1 is a valid CAS Registry Number.

Synthesis of 4-aryl-2-hydroxy-4-oxo-2-butenoic (Aroylpyruvic) acids N-(4-Acetylaminosulfonylphenyl)amides
Gein,Bobrovskaya,Sitnikova
, p. 629 - 631 (2014/06/09)
Methyl aroylpyruvates react with sodium 4-aminobenzenesulfonylacetamide in acetic acid to afford 4-aryl-2-hydroxy-4-oxo-2-butenoic acids N-(4-acetylaminosulfonylphenyl)amides. The latter were studied in reactions with hydrazine hydrate.
