900325-79-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 900325-79-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,0,3,2 and 5 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 900325-79:
(8*9)+(7*0)+(6*0)+(5*3)+(4*2)+(3*5)+(2*7)+(1*9)=133
133 % 10 = 3
So 900325-79-3 is a valid CAS Registry Number.

, 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.
