Check Digit Verification of cas no

The CAS Registry Mumber 81420-45-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,4,2 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 81420-45:
(7*8)+(6*1)+(5*4)+(4*2)+(3*0)+(2*4)+(1*5)=103
103 % 10 = 3
So 81420-45-3 is a valid CAS Registry Number.

2-Nitrophenyl Phenoxyformate, C13H9NO5

Bryant, Garold L.,King, Joseph A.

, p. 1141 - 1143 (1995)

The title mononitrodiphenyl carbonate constitutes the simplest congener in the arylnitrocarbonate family.The structure contains two independent molecules.The two O-C (ester) bond lengths average 1.340(7) (phenyl) and 1.354(6) Angstroem (nitrophenyl).The average C=O (carbonyl) bond length is 1.180(7) Angstroem.In both molecules there is a close intramolecular interaction between an O atom of the nitro group and the carbonyl C atom.The configuration and the average C...O distance are similar to those observed in other nitrophenyl carbonate structures.
