1,4-Diphenyl-norborn-5-ene-2endo,3endo-dicarboxylic acid-anhydride is a complex organic compound with the molecular formula C23H20O3. It is derived from norbornane, a bicyclic hydrocarbon, and features two phenyl groups attached at the 1 and 4 positions. The compound has a norborn-5-ene structure with a double bond between the 5 and 6 carbons, and two carbonyl groups at the 2 and 3 positions, which are part of an anhydride functional group. This anhydride group is formed by the removal of a water molecule from two carboxylic acid groups. The compound is of interest in organic chemistry due to its unique structure and potential applications in the synthesis of various pharmaceuticals and materials. It is characterized by its stability and reactivity, which can be influenced by the steric and electronic effects of the phenyl groups and the anhydride functionality.
The CAS Registry Mumber 5079-96-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,7 and 9 respectively; the second part has 2 digits, 9 and 6 respectively. Calculate Digit Verification of CAS Registry Number 5079-96: (6*5)+(5*0)+(4*7)+(3*9)+(2*9)+(1*6)=109 109 % 10 = 9 So 5079-96-9 is a valid CAS Registry Number.
