Check Digit Verification of cas no
The CAS Registry Mumber 33857-20-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,8,5 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 33857-20:
(7*3)+(6*3)+(5*8)+(4*5)+(3*7)+(2*2)+(1*0)=124
124 % 10 = 4
So 33857-20-4 is a valid CAS Registry Number.

Inhibitors of cholesterol biosynthesis. 2. Hypocholesterolemic and antioxidant activities of benzopyran and tetrahydronaphthalene analogues of the tocotrienols
Pearce,Parker,Deason,Dischino,Gillespie,Qureshi,Volk,Wright
, p. 526 - 541 (2007/10/02)
Tocotrienols exhibit antioxidant and cholesterol-biosynthesis-inhibitory activities and may be of value as antiatherosclerotic agents. The mechanism of their hypolipidemic action involves posttranscriptional suppression of HMG-CoA reductase (HMGR) in a ma
