Check Digit Verification of cas no

The CAS Registry Mumber 83268-65-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,2,6 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 83268-65:
(7*8)+(6*3)+(5*2)+(4*6)+(3*8)+(2*6)+(1*5)=149
149 % 10 = 9
So 83268-65-9 is a valid CAS Registry Number.

Structural Modification of Mevinolin

Lee, Ta-Jyh,Holtz, Willbur J.,Smith, Robert L.

, p. 4750 - 4757 (2007/10/02)

Synthetic strategies are described for modifying the side-chain ester and lactone moieties of mevinolin (1), a potent, competitive HMG-CoA reductase inhibitor isolated from cultures of Aspergillus terreus.A general route for preparing side-chain ether analogues of 1 is disclosed.Central to the success of this multistep route is the use of a method for reversibly masking the lactone moiety as a hemiacetal ether.The merit of this strategy is demonstrated again in the route developed for elaborating mevalonate analogue 11 from 1.Finally, a new, versatile, and efficientmethod is presented for homologating five- and six-membered lactones and is used to prepare carboxylate 27, a homologue of 1.
