Check Digit Verification of cas no

The CAS Registry Mumber 93351-75-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,3,5 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 93351-75:
(7*9)+(6*3)+(5*3)+(4*5)+(3*1)+(2*7)+(1*5)=138
138 % 10 = 8
So 93351-75-8 is a valid CAS Registry Number.

Synthesis and modeling studies with monocyclic analogues of mycophenolic acid

Anderson, Wayne K.,Boehm, Terri L.,Makara, Gergely M.,Swann, R. Thomas

, p. 46 - 55 (1996)

Two stepwise procedures, developed for the introduction of the (E)-4- methyl-4-hexenoic acid side chain of mycophenolic acid, were used in the synthesis of monocyclic mycophenolic acid analogues 2a-i. The derivatives with a methyl group or hydrogen at C-4 and lacking the lactone moiety were much less cytotoxic than mycophenolic acid. The menocyclic analogues with a C-4 chloro group did show some activity, albeit much less than mycophenolic acid. The observed differences in potency are rationalized by semiempirical calculations of intramolecular H-bonds.
