Check Digit Verification of cas no

The CAS Registry Mumber 77929-48-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,9,2 and 9 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 77929-48:
(7*7)+(6*7)+(5*9)+(4*2)+(3*9)+(2*4)+(1*8)=187
187 % 10 = 7
So 77929-48-7 is a valid CAS Registry Number.

SYNTHESIS OF UROPORPHYRIN-III, AND RELATED HEPTA- AND PENTA-CARBOXYLIC PORPHYRINS BY MODIFICATIONS OF THE MACDONALD METHOD

Chakrabarty, M.,Ali, S. A.,Philip, G.,Jackson, A. H.

, p. 1199 - 1204 (2007/10/02)

A modification of the MacDonald route has been developed in which all four pyrrole units of uroporphyrin-III have been derived from the same conveniently prepared starting pyrrole.Related hepta- and penta-carboxylic porphyrins have also been synthesised by condensation of appropriate α-formyl pyrromethane-α'-carboxylic acids; in each case other porphyrins with different numbers of acidic side-chains were also produced but the desired products were easily separated (as their methyl esters) by h.p.l.c.
