17β-(2'-tetrahydropyranyloxy)androst-4-en-3-one is a chemical compound with the molecular formula C21H32O2. It is a steroidal ketone derivative, specifically a 4-en-3-one, which means it has a double bond at the 4th carbon and a ketone group at the 3rd carbon. The compound features a tetrahydropyranyl (THP) protecting group at the 17β position, which is a common protecting group used in organic synthesis to shield hydroxyl groups. This particular compound is a synthetic intermediate often used in the preparation of various steroidal drugs and hormones, due to its ability to be further functionalized and modified. The THP group can be selectively removed under mild acidic conditions, allowing for the controlled deprotection of the steroidal molecule.

516-63-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 516-63-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,1 and 6 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 516-63:
(5*5)+(4*1)+(3*6)+(2*6)+(1*3)=62
62 % 10 = 2
So 516-63-2 is a valid CAS Registry Number.
