The chemical compound "(3R,5R,6S,8S,9S,10R,13S,14S,17S)-17-((R)-1-Hydroxy-ethyl)-10,13-dimethyl-hexadecahydro-cyclopenta[a]phenanthrene-3,6-diol" is a complex, chiral molecule with a unique structure. It belongs to the class of organic compounds known as cycloalkanes, specifically a cyclopenta[a]phenanthrene derivative. (3R,5R,6S,8S,9S,10R,13S,14S,17S)-17-((R)-1-Hydroxy-ethyl)-10,13-dimethyl-hexadecahydro-cyclopenta[a]phenanthrene-3,6-diol is characterized by its 17-carbon atoms, which form a cyclopenta[a]phenanthrene ring system, and the presence of two hydroxyl groups at the 3 and 6 positions. Additionally, it features a hydroxyethyl group at the 17th position and two methyl groups at the 10th and 13th positions. The stereochemistry of the molecule is defined by the presence of multiple chiral centers, indicated by the 'R' and 'S' prefixes, which denote the specific three-dimensional arrangement of the atoms around these centers. (3R,5R,6S,8S,9S,10R,13S,14S,17S)-17-((R)-1-Hydroxy-ethyl)-10,13-dimethyl-hexadecahydro-cyclopenta[a]phenanthrene-3,6-diol's structure and properties make it a potentially interesting candidate for further study in various fields, such as pharmaceuticals or materials science, due to its unique stereochemistry and cyclic structure.
The CAS Registry Mumber 4352-09-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,5 and 2 respectively; the second part has 2 digits, 0 and 9 respectively. Calculate Digit Verification of CAS Registry Number 4352-09: (6*4)+(5*3)+(4*5)+(3*2)+(2*0)+(1*9)=74 74 % 10 = 4 So 4352-09-4 is a valid CAS Registry Number.
