21-Fluoro-3β-hydroxypregn-5-en-20-one is a synthetic steroid compound that belongs to the pregnane family. It is characterized by the presence of a fluorine atom at the 21st position, a hydroxyl group at the 3β position, and a double bond between the 5th and 6th carbon atoms. This chemical structure is derived from the natural steroid pregnane, which is a precursor to various hormones and other biologically active compounds. The fluorination at the 21st position and the hydroxylation at the 3β position are modifications that can alter the compound's pharmacological properties, potentially enhancing its activity or selectivity. 21-fluoro-3β-hydroxypregn-5-en-20-one is of interest in medicinal chemistry and drug development due to its potential therapeutic applications, particularly in the areas of inflammation and immune response modulation.

Check Digit Verification of cas no

The CAS Registry Mumber 434-17-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,3 and 4 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 434-17:
(5*4)+(4*3)+(3*4)+(2*1)+(1*7)=53
53 % 10 = 3
So 434-17-3 is a valid CAS Registry Number.
