5,10-Dihydrodinaphtho[1,2,3-cd:3',2',1'-lm]perylene is a complex organic compound with a molecular formula of C32H18. It is a derivative of perylene, a polycyclic aromatic hydrocarbon consisting of two naphthalene units fused together. This specific compound features a dihydro (two hydrogen atoms added) modification at the 5,10 positions, which slightly alters its chemical properties compared to the parent perylene molecule. The compound is characterized by its unique structure, which includes a large, planar, and conjugated π-system, making it an interesting subject for research in the fields of organic chemistry, materials science, and potentially as a precursor for the synthesis of other complex organic molecules.
The CAS Registry Mumber 81-31-2 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 1 respectively; the second part has 2 digits, 3 and 1 respectively. Calculate Digit Verification of CAS Registry Number 81-31: (4*8)+(3*1)+(2*3)+(1*1)=42 42 % 10 = 2 So 81-31-2 is a valid CAS Registry Number.
