80097-52-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80097-52-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,0,9 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 80097-52:
(7*8)+(6*0)+(5*0)+(4*9)+(3*7)+(2*5)+(1*2)=125
125 % 10 = 5
So 80097-52-5 is a valid CAS Registry Number.

, (2008/06/13)
Enol acetylation is carried out on a variety of 1,4,6-trien-3-ones to form 1,3,5,7 tetraene structures from which 1α-hydroxy-7-dehydro steroids are obtained. The compounds are intermediates used in the preparation of vitamin D3 metabolites such as 1α,25-dihydroxyvitamin D3 and 1α-hydroxyvitamin D3.
