Check Digit Verification of cas no

The CAS Registry Mumber 140424-59-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,4,2 and 4 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 140424-59:
(8*1)+(7*4)+(6*0)+(5*4)+(4*2)+(3*4)+(2*5)+(1*9)=95
95 % 10 = 5
So 140424-59-5 is a valid CAS Registry Number.

FIVE-MEMBERED 2,3-DIOXOHETEROCYCLES. XXI. SYNTHESIS OF 1,5-DIARYL-4-TERT-BUTOXYCARBONYL-3-HYDROXY-2,5-DIHYDRO-2-PYRROLONES AND THEIR REACTION WITH ARYLAMINES AND o-PHENYLENEDIAMINE

Gein, V. L.,Voronina, E. V.,Andreichikov, Yu. S.

, p. 1722 - 1729 (2007/10/02)

The reaction of di-tert-butyl oxaloacetate or its potassium salt with Schiff bases gave 1,5-diaryl-4-tert-butoxycarbonyl-3-hydroxy-2,5-dihydro-2-pyrrolones.Reaction of the latter with arylamines led to N-aryl-1,5-diaryl-3-hydroxy-2-oxo-4-pyrrolecarboxamides.The reaction with o-phenylenediamine gave 2,3-diaryl-1,4-dioxo-5H,10H-1,3-dihydropyrrolo-1,5-benzodiazepines.
