The chemical "9-fluoro-11β,21-dihydroxy-16α,17-isopropylidenedioxy-2'-phenyl-(5α)-pregnano[3,2-c]pyrazol-20-one" is a complex steroidal compound with a unique molecular structure. It features a pregnane core, which is a type of steroid, and is characterized by the presence of a pyrazol ring fused to the steroid nucleus. The molecule contains several functional groups, including a fluorine atom at the 9-position, two hydroxyl groups at the 11β and 21 positions, and an isopropylidenedioxy group at the 16α and 17 positions. Additionally, it has a phenyl group at the 2' position, which is part of the pyrazol ring. 9-fluoro-11β,21-dihydroxy-16α,17-isopropylidenedioxy-2'-phenyl-(5α)-pregnano[3,2-c]pyrazol-20-one is a derivative of the pregnane family and may have potential applications in medicinal chemistry, particularly in the development of drugs targeting the endocrine system. Its specific biological activity and pharmacological properties would need to be further investigated through experimental studies.
The CAS Registry Mumber 5758-43-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,5 and 8 respectively; the second part has 2 digits, 4 and 3 respectively. Calculate Digit Verification of CAS Registry Number 5758-43: (6*5)+(5*7)+(4*5)+(3*8)+(2*4)+(1*3)=120 120 % 10 = 0 So 5758-43-0 is a valid CAS Registry Number.
