(3aR,4R,5R,6aS)-5-(Biphenyl-4-carbonyloxy)-2-oxo-hexahydro-cyclopenta[b]furan-4-carboxylic acid methyl ester is a complex organic compound with the molecular formula C21H20O6. It features a cyclopenta[b]furan core structure, which is a five-membered ring with a furan (oxygen-containing) ring fused to a cyclopentane (five-carbon) ring. The compound has a biphenyl-4-carbonyloxy group attached to the 5-position, which is a benzene ring connected to another benzene ring at the 4-position, with a carbonyl (C=O) group. Additionally, it has a methyl ester group, indicating the presence of a -COOCH3 functional group. This molecule is characterized by its chiral centers at positions 3a, 4, 5, and 6a, which give it a specific three-dimensional arrangement in space. The compound is likely to be used in the synthesis of pharmaceuticals or other specialty chemicals due to its intricate structure and functional groups.

Check Digit Verification of cas no

The CAS Registry Mumber 79308-34-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,3,0 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 79308-34:
(7*7)+(6*9)+(5*3)+(4*0)+(3*8)+(2*3)+(1*4)=152
152 % 10 = 2
So 79308-34-2 is a valid CAS Registry Number.

An alternative synthesis of the Corey prostaglandin aldehyde.

Peel,Sutherland

, p. 151 - 153 (1974)

This is a detailed description of 1 route to the chemical synthesis of PGs (prostaglandins) and their analogs in the laboratory. The chemical formula and chemical structure of each step in the chain is diagrammed. The aldehyde had served as intermediary in the synthesizing process in previous experiments. In this series of steps, the starting stage was the Prins reaction of norbornadiene and paraform-aldehyde in formic acid. Lactones were used as starting materials in the synthesis. Hydrolysis and oxidation were used to change 1 substance in the process into the next.
