Check Digit Verification of cas no

The CAS Registry Mumber 123730-90-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,7,3 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 123730-90:
(8*1)+(7*2)+(6*3)+(5*7)+(4*3)+(3*0)+(2*9)+(1*0)=105
105 % 10 = 5
So 123730-90-5 is a valid CAS Registry Number.

INTRAMOLECULAR N- AND O-IMIDOYLATION OF THE CARBOXAMIDE GROUP

Mazurkiewicz, Roman

, p. 115 - 125 (2007/10/02)

N,N'-Disubstituted diamides of dicarboxylic acids have been found to react with Ph3PBr2 to form intramolecular N-imidoylation products (5- or 6-iminolactams); only from N,N'-diphenylmaleamide the O-imidoylation product (N,N'-diphenylmaleimidic anhydride 6) was obtained.The imidic anhydride 6 in CH2Cl2 solution, in the presence of HBr undergoes a rearrangement to the respective iminolactam.Possible mechanisms of these reactions are discussed.Both the 13C NMR and 1H NMR spectra indicated the presence of Z,Z and Z,E-isomers in the imidic anhydride 6.
