The chemical compound "(3aR)-5t-ethoxycarbonyloxy-7c-hydroxy-2,2-dimethyl-(3ar,7ac)-hexahydro-benzo[1,3]dioxole-5c-carboxylic acid methyl ester" is a complex organic molecule with a unique structure. It features a hexahydro-benzo[1,3]dioxole core, which is a type of benzene ring fused with an oxygen-containing ring. The compound has a 5c-carboxylic acid group, which is esterified with a methyl group, and a 7c-hydroxy group, indicating the presence of a hydroxyl group at the 7c position. Additionally, it has an ethoxycarbonyloxy group at the 5t position, which is an ester of a carboxylic acid with an ethoxycarbonyl group. The 2,2-dimethyl groups indicate two methyl groups attached to the same carbon atom, contributing to the molecule's branching. The stereochemistry is specified as 3aR, indicating the configuration of the molecule at the 3a position. (3aR)-5t-ethoxycarbonyloxy-7c-hydroxy-2,2-dimethyl-(3ar,7ac)-hexahydro-benzo[1,3]dioxole-5c-carboxylic acid methyl ester is likely to be found in the field of organic chemistry, potentially as an intermediate in the synthesis of pharmaceuticals or other complex organic compounds.
The CAS Registry Mumber 5783-35-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,8 and 3 respectively; the second part has 2 digits, 3 and 5 respectively. Calculate Digit Verification of CAS Registry Number 5783-35: (6*5)+(5*7)+(4*8)+(3*3)+(2*3)+(1*5)=117 117 % 10 = 7 So 5783-35-7 is a valid CAS Registry Number.
