Check Digit Verification of cas no

The CAS Registry Mumber 631880-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,1,8,8 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 631880-99:
(8*6)+(7*3)+(6*1)+(5*8)+(4*8)+(3*0)+(2*9)+(1*9)=174
174 % 10 = 4
So 631880-99-4 is a valid CAS Registry Number.

Synthesis of 1-aryl-2-[2-(dimethylamino)ethyl]-1,2-dihydrochromeno[2,3-c] pyrrole-3,9-diones and their analogs

Vydzhak,Panchishyn

, p. 323 - 329 (2010)

Methyl o-hydroxybenzoylpyruvate heated with N,N-dimethylethylenediamine and aromatic aldehydes affords in a high yield 5-aryl-3-hydroxy-4-(2-hydroxyphenyl) -1-[2-(dimethylamino)ethyl]-1,5-dihydro-2H-pyrrol-2-ones, which easily split off water at boiling in acetic acid and are converted into 1-aryl-2-[(2- dimethylamino)ethyl]-1,2-dihydrochromeno[2,3-c]pyrrol-3,9-diones. The developed route of synthesis provides a wide range of derivatives of 1-aryl-2-[ω- (dialkylamino)alkyl]-1,2-dihydrochromeno[2,3-c]pyrrole-3,9-diones.
