169305-52-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 169305-52-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,9,3,0 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 169305-52:
(8*1)+(7*6)+(6*9)+(5*3)+(4*0)+(3*5)+(2*5)+(1*2)=146
146 % 10 = 6
So 169305-52-6 is a valid CAS Registry Number.

Selective acylation of A-ring precursors of vitamin D using enzymes in organic solvents

Fernandez,Ferrero,Gotor,Okamura

, p. 6057 - 6061 (2007/10/03)

Whereas Chromobacterium viscosum lipase (CVL) catalyzes selectively the acylation of the C-5 hydroxyl of the three stereoisomeric vitamin D A-ring precursors 2a, 3a and 3b, only the C-3 hydroxyl of the fourth stereoisomer 2b is acylated under the same conditions in organic solvent. In a convenient application, the racemic vitamin D A-ring precursor 4, possessing only the C-5 hydroxyl, was resolved using suitable conditions identified from the studies of 2 and 3.
