Check Digit Verification of cas no

The CAS Registry Mumber 146071-72-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,0,7 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 146071-72:
(8*1)+(7*4)+(6*6)+(5*0)+(4*7)+(3*1)+(2*7)+(1*2)=119
119 % 10 = 9
So 146071-72-9 is a valid CAS Registry Number.

1H and 13C NMR Study of 2,3-Dicarboxymethyl-7-oxabicyclohepta-2,5-diene Derivatives

Bighelli, Ange,Tomi, Felix,Casanova, Joseph

, p. 1268 - 1270 (1992)

13C and 1H NMR spectral assignments have been obtained for 2,3-dicarboxymethyl-7-oxabicyclohepta-2,5-diene and 19 of its derivatives.The use of a combination of one-dimensional NMR techniques allowed the unambiguous assignments of all 13C resonances of the bicyclic framework.key words: 1H NMR, 13C NMR, XHCORR, INADEQUATE, oxanorbornadiene derivatives
