The chemical compound "(+/-)-4c,6t-dibromo-2,2-dimethyl-(3ar,6ac)-tetrahydro-cyclopenta[1,3]dioxole" is a complex organic molecule with a unique structure. It features a cyclopenta[1,3]dioxole ring, which is a five-membered ring with two oxygen atoms in a 1,3-relationship. The molecule is characterized by the presence of two bromine atoms at the 4 and 6 positions, and a dimethyl group at the 2 position. The "tetrahydro" prefix indicates that the molecule has four hydrogen atoms added to the ring structure, which are not part of the aromatic system. The "3ar,6ac" notation suggests the specific arrangement of the atoms in the molecule, with "ar" and "ac" likely referring to the axial and equatorial positions, respectively. (+/-)-4c,6t-dibromo-2,2-dimethyl-(3ar,6ac)-tetrahydro-cyclopenta[1,3]dioxole is a racemic mixture, indicated by the "(+/-)" prefix, meaning it contains equal amounts of both the R and S enantiomers. The compound's properties, such as solubility, reactivity, and potential applications, would be influenced by its stereochemistry and the presence of the bromine atoms.
The CAS Registry Mumber 4159-65-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,5 and 9 respectively; the second part has 2 digits, 6 and 5 respectively. Calculate Digit Verification of CAS Registry Number 4159-65: (6*4)+(5*1)+(4*5)+(3*9)+(2*6)+(1*5)=93 93 % 10 = 3 So 4159-65-3 is a valid CAS Registry Number.
