Check Digit Verification of cas no

The CAS Registry Mumber 92998-75-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,9,9 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 92998-75:
(7*9)+(6*2)+(5*9)+(4*9)+(3*8)+(2*7)+(1*5)=199
199 % 10 = 9
So 92998-75-9 is a valid CAS Registry Number.

FIVE INGOL ESTERS AND A 17-HYDROXYINGENOL ESTER FROM THE LATEX OF EUPHORBIA KAMERUNICA. ASSIGNMENT OF ESTERS USING 13C N.M.R. METHODS.

Connolly, Joseph D.,Fakunle, Christopher O.,Rycroft, David S.

, p. 3773 - 3776 (1984)

The structures of five ingol esters and a 17-hydroxyingenol ester from the latex of Euphorbia kamerunica have been determined.The 13C n.m.r. spectra of these compounds have been assigned using 2D δC/δH correlations.The specific positions of attachment of esters have been assigned unambiguously using 13C n.m.r. methods including 2D long range δC/δH correlations.
