Indeno[1,2,3-cd]pyrene-11,12-dicarboxylic acid-anhydride is a complex organic compound with the chemical formula C24H10O3. It is a derivative of indeno[1,2,3-cd]pyrene, a polycyclic aromatic hydrocarbon (PAH) consisting of five fused benzene rings and one five-membered ring. The anhydride form of the compound features two carboxylic acid groups (-COOH) at the 11 and 12 positions, which are connected by an anhydride bridge, resulting in the loss of a water molecule (H2O). This chemical is of interest in the field of organic chemistry and environmental science, as it can be a product of incomplete combustion processes and may have potential applications in the synthesis of various compounds. However, due to its complex structure and potential environmental impact, further research is needed to fully understand its properties and behavior.
The CAS Registry Mumber 5695-26-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,9 and 5 respectively; the second part has 2 digits, 2 and 6 respectively. Calculate Digit Verification of CAS Registry Number 5695-26: (6*5)+(5*6)+(4*9)+(3*5)+(2*2)+(1*6)=121 121 % 10 = 1 So 5695-26-1 is a valid CAS Registry Number.
