(20Ξ)-3,3-ethanediyldioxy-6β-fluoro-5-hydroxy-16α-methyl-17,20;20,21-bis-methylenedioxy-5α-pregnan-11-one is a complex steroidal compound with a unique molecular structure. It features a pregnane core, which is a type of steroid with a specific carbon skeleton. The molecule is characterized by the presence of a 6β-fluoro substitution, which introduces a fluorine atom at the 6β position, and a 5-hydroxy group, indicating a hydroxyl group at the 5th carbon. Additionally, it has a 16α-methyl group, which is a methyl group attached at the 16α position, and a 3,3-ethanediyldioxy group, suggesting the presence of an ethylene glycol ether linkage. The 17,20;20,21-bis-methylenedioxy part of the name indicates two separate methylene dioxy bridges, one between carbons 17 and 20, and another between carbons 20 and 21. (20Ξ)-3,3-ethanediyldioxy-6β-fluoro-5-hydroxy-16α-methyl-17,20;20,21-bis-methylenedioxy-5α-pregnan-11-one also has a 5α-pregnan-11-one structure, which means it has a ketone group at the 11th carbon and is in the 5α configuration. Overall, this chemical is a highly functionalized steroid with potential applications in medicine and pharmaceuticals, given its complex and specific structure.
The CAS Registry Mumber 2802-31-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,0 and 2 respectively; the second part has 2 digits, 3 and 1 respectively. Calculate Digit Verification of CAS Registry Number 2802-31: (6*2)+(5*8)+(4*0)+(3*2)+(2*3)+(1*1)=65 65 % 10 = 5 So 2802-31-5 is a valid CAS Registry Number.
