The chemical compound "(3aR,4R,5R,6aS)-5-(tert-Butyl-dimethyl-silanyloxy)-4-[(E)-(S)-5-phenyl-3-(tetrahydro-pyran-2-yloxy)-pent-1-enyl]-hexahydro-cyclopenta[b]furan-2-ol" is a complex, chiral molecule with a unique structure. It features a cyclopenta[b]furan-2-ol core, which is a five-membered ring fused to a furan ring. The molecule has a hexahydro (six hydrogen atoms) substituent attached to the cyclopenta[b]furan-2-ol, indicating a partially saturated structure. A tert-butyl-dimethyl-silanyloxy group is present at the 5-position, providing steric hindrance and protecting the hydroxyl group. The 4-position is occupied by a long, unsaturated side chain that includes a phenyl group, a tetrahydro-pyran-2-yloxy group, and a double bond, which contributes to the molecule's overall geometry and reactivity. The compound's stereochemistry is defined by the (3aR,4R,5R,6aS) configuration, which specifies the three-dimensional arrangement of atoms around the chiral centers. This complex structure likely influences its physical and chemical properties, making it a subject of interest in organic chemistry and potentially in pharmaceutical applications due to its intricate stereochemistry and functional groups.
The CAS Registry Mumber 85235-23-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,2,3 and 5 respectively; the second part has 2 digits, 2 and 3 respectively. Calculate Digit Verification of CAS Registry Number 85235-23: (7*8)+(6*5)+(5*2)+(4*3)+(3*5)+(2*2)+(1*3)=130 130 % 10 = 0 So 85235-23-0 is a valid CAS Registry Number.
