Check Digit Verification of cas no

The CAS Registry Mumber 81189-93-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,1,8 and 9 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 81189-93:
(7*8)+(6*1)+(5*1)+(4*8)+(3*9)+(2*9)+(1*3)=147
147 % 10 = 7
So 81189-93-7 is a valid CAS Registry Number.

A new method for the synthesis of antihypercholesterolemic agent simvastatin

Dabak, Kadir,Adiyaman, Mustafa

, p. 673 - 677 (2003)

A new synthetic method for the preparation of the cholesterol-lowering drug simvastatin from the naturally occurring lovastatin is reported. The synthesis employs first the protection of the OH group of lovastatin (1) and then the protection of the lactone C=O group to prevent enolization via conversion to the orthoesters 4a and 4b. Alkylation of the 2-methylbutyrate side chain is then successfully achieved. Removal of the protecting groups affords antihypercholesterolemic agent simvastatin (2).

Synthesis and biological evaluation of lovastatin-derived aliphatic hydroxamates that induce reactive oxygen species

Some hydroxamate compounds induce cancer cell death by intracellular reactive oxygen species (ROS). This study introduced the hydroxamate core into lovastatin, a fungus metabolite clinically used for the treatment of hypercholesterolemia. The resulting co
