2-Oxo-17β-acetoxy-9(10-5β)-abeo-Δ1(10),3-androstadien is a complex steroidal chemical compound derived from the androstane family. It features a unique structure with a 9(10-5β)-abeo configuration, indicating a rearrangement of the carbon skeleton compared to the standard androstane structure. The molecule contains a 2-oxo group, which is a carbonyl group at the 2-position, and a 17β-acetoxy group, which is an acetate ester at the 17β position. The Δ1(10),3 notation signifies the presence of a double bond between carbons 1 and 3, with the 1-position being part of a cyclopentane ring. 2-Oxo-17β-acetoxy-9(10-5β)-abeo-Δ1(10),3-androstadien is of interest in the field of organic chemistry and may have potential applications in pharmaceuticals or as an intermediate in the synthesis of other steroidal compounds.
The CAS Registry Mumber 2456-09-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,5 and 6 respectively; the second part has 2 digits, 0 and 9 respectively. Calculate Digit Verification of CAS Registry Number 2456-09: (6*2)+(5*4)+(4*5)+(3*6)+(2*0)+(1*9)=79 79 % 10 = 9 So 2456-09-9 is a valid CAS Registry Number.
