The chemical compound "10-(2,4,6-trimethyl-phenyl)-10H-5,10-ethano-acridarsine-11r,12c-dicarboxylic acid anhydride" is a complex organic molecule with a unique structure. It features a 10-membered acridine ring system, which is a fused ring structure composed of a benzene ring and a pyridine ring. The compound is characterized by the presence of a 2,4,6-trimethyl-phenyl group attached to the 10th position of the acridine ring, which contributes to its stability and reactivity. The ethano bridge connects the 5th and 10th positions of the acridine ring, and the compound also includes two carboxylic acid groups at the 11r and 12c positions, which are capable of forming an anhydride. This anhydride formation is significant as it allows the molecule to participate in various chemical reactions, such as esterification and amidation, making it a potentially useful building block in organic synthesis and pharmaceutical chemistry.
The CAS Registry Mumber 70299-43-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,2,9 and 9 respectively; the second part has 2 digits, 4 and 3 respectively. Calculate Digit Verification of CAS Registry Number 70299-43: (7*7)+(6*0)+(5*2)+(4*9)+(3*9)+(2*4)+(1*3)=133 133 % 10 = 3 So 70299-43-3 is a valid CAS Registry Number.
