Check Digit Verification of cas no

The CAS Registry Mumber 72228-32-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,2,2 and 8 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 72228-32:
(7*7)+(6*2)+(5*2)+(4*2)+(3*8)+(2*3)+(1*2)=111
111 % 10 = 1
So 72228-32-1 is a valid CAS Registry Number.

Chemistry of diazopolycarbonyl compounds: V. Synthesis, structure, and chemical characteristics of aryl diazoacetates

Zalesov,Kataev

, p. 1666 - 1672 (2007/10/03)

Aryl diazoacetates were prepared, and basing on spectral data and quantum-chemical calculations cis-trans isomerism thereof was proved. The reactions of diazoesters with hydrochloric and sulfuric acids, triphenylphosphine, and dinitrogen tetroxide resulted respectively in aryl chloroacetates, bis(aryloxy-carbonylmethyl) sulfates, triphenylphosphoranylidenehydrazones of aryl 2-oxoethanoates, and N-oxides of diaryl 1,2,5-oxadiazole-3,4-dicarboxylates.
