The chemical compound "6α,7α-Diacetoxy-4α,9-epoxy-15α-[(R)-2-methyl-1-oxobutoxy]-3β-[[(Z)-2-methyl-1-oxo-2-butenyl]oxy]cevane-4,14,16β,20-tetrol" is a complex organic molecule characterized by its unique structure and functional groups. It features a cevane skeleton, which is a type of triterpenoid, a large class of naturally occurring organic compounds derived from isoprene units. This specific compound is further defined by the presence of four hydroxyl groups (-OH) at the 4, 14, 16β, and 20 positions, an epoxy group between carbons 4 and 9, and two acetoxy groups (-OAc) at the 6α and 7α positions. Additionally, it has a (R)-2-methyl-1-oxobutoxy group at the 15α position and a (Z)-2-methyl-1-oxo-2-butenyloxy group at the 3β position, indicating the presence of a double bond in the latter group. The compound's complexity arises from the combination of these functional groups and the stereochemistry at specific carbon centers, which can significantly influence its biological activity and reactivity.
The CAS Registry Mumber 663-93-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,6 and 3 respectively; the second part has 2 digits, 9 and 3 respectively. Calculate Digit Verification of CAS Registry Number 663-93: (5*6)+(4*6)+(3*3)+(2*9)+(1*3)=84 84 % 10 = 4 So 663-93-4 is a valid CAS Registry Number.
