17α-Hydroxy-19-nor-pregnen-(5(10))-dion-(3,20) is a complex steroidal compound with the molecular formula C20H28O3. It is derived from the pregnane family of steroids, which are characterized by a cyclopentanophenanthrene ring system. This specific compound features a 17α-hydroxyl group, indicating the presence of a hydroxyl group at the 17α position, and a 19-nor structure, which means that one carbon atom is missing at the 19th position compared to the standard pregnane structure. The numbering of the double bonds as (5(10))-dion-(3,20) indicates the presence of a double bond between carbons 5 and 10, and another between carbons 3 and 20, with both positions being part of a dione structure, suggesting the presence of two carbonyl groups. 17α-Hydroxy-19-nor-pregnen-(5(10))-dion-(3,20) is of interest in the field of organic chemistry and may have potential applications in pharmaceuticals or as an intermediate in the synthesis of other steroidal compounds.

5251-19-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5251-19-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,5 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.Calculate Digit Verification of CAS Registry Number 5251-19:
(6*5)+(5*2)+(4*5)+(3*1)+(2*1)+(1*9)=74
74 % 10 = 4
So 5251-19-4 is a valid CAS Registry Number.
