(+/-)-7-syn-bromo-3-endo-hydroxy-2-oxa-norbornane-5-endo,6-endo-dicarboxylic acid-5-lactone is a complex organic compound with a unique molecular structure. It is characterized by the presence of a norbornane core, which is a bicyclic structure consisting of two fused cyclohexane rings. The compound features a 2-oxa group, which is an oxygen atom replacing one of the carbon atoms in the norbornane structure. Additionally, it contains a 5-endo,6-endo-dicarboxylic acid group, which provides two carboxylic acid functionalities at the 5 and 6 positions. The 7-syn position is occupied by a bromine atom, while the 3-endo position has a hydroxyl group. The compound also has a 5-lactone ring, which is a cyclic ester formed by the intramolecular esterification of the carboxylic acid group at the 5 position with the hydroxyl group at the 3 position. Overall, (+/-)-7syn-bromo-3endo-hydroxy-2-oxa-norbornane-5endo,6endo-dicarboxylic acid-5-lactone is a brominated, hydroxylated, and lactonized derivative of norbornane, with potential applications in various chemical and pharmaceutical research areas.
The CAS Registry Mumber 6028-65-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,0,2 and 8 respectively; the second part has 2 digits, 6 and 5 respectively. Calculate Digit Verification of CAS Registry Number 6028-65: (6*6)+(5*0)+(4*2)+(3*8)+(2*6)+(1*5)=85 85 % 10 = 5 So 6028-65-5 is a valid CAS Registry Number.
