Oxido[10]annulene, also known as 10-oxa-1,2,3,4,5,6,7,8,9-decahydropyrene, is a polycyclic aromatic compound consisting of a 10-membered ring with one oxygen atom incorporated into the structure. It is a derivative of annulene, a class of cyclic, planar polyenes with delocalized π-electron systems. The presence of the oxygen atom in oxido[10]annulene introduces a heteroatom into the molecule, which can affect its electronic properties and reactivity compared to its parent annulene. Oxido[10]annulene has potential applications in materials science and organic chemistry, particularly in the synthesis of more complex heterocycles and as a building block for functional materials.
The CAS Registry Mumber 4759-11-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,5 and 9 respectively; the second part has 2 digits, 1 and 1 respectively. Calculate Digit Verification of CAS Registry Number 4759-11: (6*4)+(5*7)+(4*5)+(3*9)+(2*1)+(1*1)=109 109 % 10 = 9 So 4759-11-9 is a valid CAS Registry Number.
