Check Digit Verification of cas no

The CAS Registry Mumber 76996-62-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,9,9 and 6 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 76996-62:
(7*7)+(6*6)+(5*9)+(4*9)+(3*6)+(2*6)+(1*2)=198
198 % 10 = 8
So 76996-62-8 is a valid CAS Registry Number.

Synthesis and structural characterization of regiocontrolled oligomers from 2-naphthalensulfonic acid and formaldehyde

Arduini,Pavan,Pochini,Ungaro,Corno

, p. 3613 - 3620 (1990)

Regiocontrolled synthesis of symmetrical dinuclear products 4 and 8 derived from condensation of 2-naphthalensulfonic acid and formaldehyde was afforded. Acid catalyzed reaction of 4 with formaldehyde gave a mixture of regiocontrolled oligomers with even number of naphthalenic nucleus from which tetranuclear 9 and hexanuclear 10 products were separated. NMR Studies of all these products were carried out, obtaining both the structural characterization and useful informations for the identification of more complex mixtures.
