(20Ξ)-6α-fluoro-11β-hydroxy-16α-methyl-17,20;20,21-bis-methylenedioxy-pregn-4-en-3-one is a complex steroidal compound characterized by its unique molecular structure. It features a pregnane core, which is a type of steroid nucleus, with several key modifications. The presence of a fluorine atom at the 6α position and a hydroxyl group at the 11β position are notable, as these functional groups can significantly alter the compound's biological activity. Additionally, the 16α position has a methyl group, which can influence the compound's lipophilicity and metabolic stability. The 17,20;20,21 positions are bridged by a methylenedioxy group, which is a common structural element in many natural products and can contribute to the compound's reactivity and potential pharmacological properties. This specific arrangement of atoms and functional groups likely endows the compound with unique chemical and biological characteristics, making it a subject of interest in the fields of chemistry and pharmacology.
The CAS Registry Mumber 3873-76-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,7 and 3 respectively; the second part has 2 digits, 7 and 6 respectively. Calculate Digit Verification of CAS Registry Number 3873-76: (6*3)+(5*8)+(4*7)+(3*3)+(2*7)+(1*6)=115 115 % 10 = 5 So 3873-76-5 is a valid CAS Registry Number.
