The chemical compound "(10R,13R,17R)-17-((R)-1,5-Dimethyl-hexyl)-10,13-dimethyl-6-nitro-2,3,4,7,8,9,10,11,12,13,14,15,16,17-tetradecahydro-1H-cyclopenta[a]phenanthrene" is a complex, naturally occurring organic molecule. It features a cyclopenta[a]phenanthrene core, which is a type of polycyclic aromatic hydrocarbon. The compound is characterized by its 17-carbon side chain, which includes a 1,5-dimethyl-hexyl group, and two methyl groups at the 10 and 13 positions. Additionally, it has a nitro group at the 6 position, which introduces a nitrogen-oxygen functional group. This molecule is a stereoisomer, with specific configurations at the 10, 13, and 17 positions, indicated by the 'R' notation, which refers to the right-handed orientation in a chiral center. The compound's structure and properties make it a subject of interest in organic chemistry and potentially in pharmaceutical research due to its complex and rigid structure.
The CAS Registry Mumber 1912-53-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,1 and 2 respectively; the second part has 2 digits, 5 and 3 respectively. Calculate Digit Verification of CAS Registry Number 1912-53: (6*1)+(5*9)+(4*1)+(3*2)+(2*5)+(1*3)=74 74 % 10 = 4 So 1912-53-4 is a valid CAS Registry Number.
