Check Digit Verification of cas no

The CAS Registry Mumber 110315-00-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,3,1 and 5 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 110315-00:
(8*1)+(7*1)+(6*0)+(5*3)+(4*1)+(3*5)+(2*0)+(1*0)=49
49 % 10 = 9
So 110315-00-9 is a valid CAS Registry Number.

5-Oxazolones, II 2,4-Diaryl-4-(2,4-dinitroaryl)-5(4H)-oxazolones: Synthesis and Acid-Catalyzed Transformation into 1-Hydroxy-1H-indazole Derivatives

D'Anello, Matteo,Erba, Emanuela,Gelmi, Maria Luisa,Pocar, Donato

, p. 67 - 74 (2007/10/02)

2,4-Diaryl-4-(2,4-dinitroaryl)-5(4 H)-oxazolones 2 were prepared by arylation of the corresponding 5(4H)-oxazolones 1 under phase-transfer conditions with the corresponding 1-halo-2,4-dinitrobenzenes. 2,4-Diaryl-4-(3,5-dinitro-2-pyridyl)-5(4H)-oxazolones 5 were obtained similarly from the corresponding 1 and 2-chloro-3,5-dinitropyridine.On reaction with methanol and p-toluenesulfonic acid , oxazolones 2 rearranged to the corresponding 1-hydroxy-1H-indazole derivatives 8.Under the same conditions oxazolones 5 afforded a mixture of the correspondingly substituted 1H-pyrazolopyridines 7 and substituted imidazopyridines 12.In all cases the solvolysis reaction, yielding substituted glycine esters 9 and 11, was competitive with the rearrangement.Reaction path are discussed.
