5-oxo-17β-propionyloxy-4-nor-3,5-secoandrostan-3-oic acid is a complex organic compound belonging to the class of steroids. It is characterized by a unique molecular structure, featuring a 4-nor-3,5-secoandrostan skeleton, which means it lacks a carbon atom at position 4 and has a broken carbon chain between positions 3 and 5. The molecule also contains a 5-oxo group, indicating the presence of a carbonyl group at position 5, and a 17β-propionyloxy group, which is a propionic acid ester attached to the 17β position. This chemical is a derivative of androstane, a naturally occurring steroid, and is known for its potential applications in pharmaceutical research, particularly in the development of drugs targeting hormonal systems. Its specific properties and reactivity are influenced by the presence of these functional groups, making it a subject of interest for chemists and biologists studying steroidal compounds.
The CAS Registry Mumber 3510-18-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,1 and 0 respectively; the second part has 2 digits, 1 and 8 respectively. Calculate Digit Verification of CAS Registry Number 3510-18: (6*3)+(5*5)+(4*1)+(3*0)+(2*1)+(1*8)=57 57 % 10 = 7 So 3510-18-7 is a valid CAS Registry Number.
