Check Digit Verification of cas no

The CAS Registry Mumber 209455-66-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,4,5 and 5 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 209455-66:
(8*2)+(7*0)+(6*9)+(5*4)+(4*5)+(3*5)+(2*6)+(1*6)=143
143 % 10 = 3
So 209455-66-3 is a valid CAS Registry Number.

Five-membered 2,3-Dioxoheterocycles. XLIV. Synthesis and Nucleophilic Reactions of 5-(β-Styryl)-2,3-dihydro-2.3-furandione

Shurov,Porvintsev,Kosvintseva,Andreichikov

, p. 1116 - 1124 (2007/10/03)

Cyclization of cinnamoylpyruvic acid results in 5-(β-styryl)-2,3-dihydro-2.3-furandione. Its reactions were studied with nucleophilic reagents: water, alcohols, acetone oxime, amines, o-aminophenol, and o-phenylenediamine. Geometric and electronic structure of cinnamoylpyruvic acid, 5-(β-styryl)-2,3-dihydro-2.3-furandione, and mechanism of formation of methyl cinnamoylpyruvate was investigated by quantum-chemical LCAO MO method in AMI approximation.
