133369-43-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133369-43-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,3,6 and 9 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 133369-43:
(8*1)+(7*3)+(6*3)+(5*3)+(4*6)+(3*9)+(2*4)+(1*3)=124
124 % 10 = 4
So 133369-43-4 is a valid CAS Registry Number.

Microbial hydroxylation and functionalization of synthetic bicyclic enones
Hammoumi,Revial,D'Angelo,Girault,Azerad
, p. 651 - 654 (1991)
The regio- and stereoselective hydroxylation of substituted octalones by various fungal strains has been evaluated. Several hydroxylated derivatives have been obtained and the potential of this method for the preparation of useful chiral synthons is discussed.
