((3aR,4R,6R,6aR)-6-Iodo-2-oxo-hexahydro-cyclopenta[b]furan-4-yl)-acetic acid is a complex organic compound characterized by its unique molecular structure. It features a cyclopenta[b]furan ring system, which is a five-membered ring fused to a furan ring. The molecule contains a 6-iodo substituent, indicating the presence of an iodine atom at the 6-position, and a 2-oxo group, which signifies a carbonyl group at the 2-position. The stereochemistry is defined by the 'R' configuration at the 3a, 4, 6, and 6a positions, which refers to the spatial arrangement of the atoms around the chiral centers. ((3aR,4R,6R,6aR)-6-Iodo-2-oxo-hexahydro-cyclopenta[b]furan-4-yl)-acetic acid is an acetic acid derivative, with the carboxyl group (-COOH) attached to the cyclopenta[b]furan framework. Such compounds can have various applications in the fields of pharmaceuticals, agrochemicals, or as intermediates in organic synthesis, due to their potential to form complex molecular interactions.
The CAS Registry Mumber 81355-36-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,3,5 and 5 respectively; the second part has 2 digits, 3 and 6 respectively. Calculate Digit Verification of CAS Registry Number 81355-36: (7*8)+(6*1)+(5*3)+(4*5)+(3*5)+(2*3)+(1*6)=124 124 % 10 = 4 So 81355-36-4 is a valid CAS Registry Number.
