The chemical compound "(8S,9S,10S,11S,13S,14S,17S)-10,13-dimethyl-17-(2-methyl-1,3-dioxolan-2-yl)hexadecahydrospiro[cyclopenta[a]phenanthrene-3,2′-[1,3]dioxolan]-11-ol" is a complex, chiral molecule with a unique structure. It features a spiro arrangement, which means it has two rings sharing a common atom. The compound consists of a cyclopenta[a]phenanthrene ring system, which is a type of polycyclic aromatic hydrocarbon, and a 1,3-dioxolan ring. The molecule has seven stereocenters, indicated by the "S" configurations at each chiral center, which contribute to its three-dimensional structure. The presence of methyl groups at the 10th and 13th positions, along with a 2-methyl-1,3-dioxolan-2-yl group at the 17th position, further define its structure. (8S,9S,10S,11S,13S,14S,17S)-10,13-dimethyl-17-(2-methyl-1,3-dioxolan-2-yl)hexadecahydrospiro[cyclopenta[a]phenanthrene-3,2′-[1,3]dioxolan]-11-ol is an example of the intricate and diverse chemistry found in natural products and synthetic organic compounds.
The CAS Registry Mumber 3754-67-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,5 and 4 respectively; the second part has 2 digits, 6 and 7 respectively. Calculate Digit Verification of CAS Registry Number 3754-67: (6*3)+(5*7)+(4*5)+(3*4)+(2*6)+(1*7)=104 104 % 10 = 4 So 3754-67-4 is a valid CAS Registry Number.
