6β-Chlor-16-methylen-17α-acetoxy-pregnen-(4)-dion-(3,20) is a complex steroidal compound characterized by its unique molecular structure. It features a pregnane core, which is a type of steroid with a four-ring structure. The compound is distinguished by the presence of a chlorine atom at the 6β position, a double bond (methylidene) at the 16 position, and an acetoxy group at the 17α position. The numbering of the carbon atoms in the structure is indicated by the (3,20) notation, which refers to the positions of the carbons in the steroid nucleus. This chemical is a derivative of pregnenolone, a naturally occurring steroid hormone, and is often used in pharmaceutical applications due to its potential biological activities. The specific modifications in the structure, such as the chlorine substitution and the acetoxy group, can significantly alter the compound's properties and effects, making it a subject of interest in medicinal chemistry and drug development.
The CAS Registry Mumber 6891-67-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,8,9 and 1 respectively; the second part has 2 digits, 6 and 7 respectively. Calculate Digit Verification of CAS Registry Number 6891-67: (6*6)+(5*8)+(4*9)+(3*1)+(2*6)+(1*7)=134 134 % 10 = 4 So 6891-67-4 is a valid CAS Registry Number.
