17α-Ethynylestra-3,17β-diol 3,17-bis(tetrahydropyranyl ether) is a complex organic compound with the molecular formula C28H38O6. It is a derivative of ethynylestradiol, a synthetic estrogen used in various pharmaceutical applications, particularly in birth control pills and hormone replacement therapy. The compound features a 17α-ethynyl group and two tetrahydropyranyl (THP) protecting groups attached to the 3 and 17β hydroxyl groups. These protecting groups are commonly used in organic synthesis to temporarily mask functional groups, allowing for selective reactions to occur at other sites within the molecule. The presence of the THP groups in 17α-ethynylestra-3,17β-diol 3,17-bis(tetrahydropyranyl ether) suggests that it is an intermediate in the synthesis of ethynylestradiol or a related pharmaceutical product, where the protecting groups can be removed under specific conditions to yield the desired active compound.

3589-92-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 3589-92-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,8 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.Calculate Digit Verification of CAS Registry Number 3589-92:
(6*3)+(5*5)+(4*8)+(3*9)+(2*9)+(1*2)=122
122 % 10 = 2
So 3589-92-2 is a valid CAS Registry Number.
