2,2,5,5-Tetraphenyl-adipic acid is a complex organic compound characterized by its molecular formula C36H26O4. It is a derivative of adipic acid, which is a dicarboxylic acid, with four phenyl groups attached to the carbon atoms at positions 2, 2, 5, and 5. 2,2,5,5-tetraphenyl-adipic acid is known for its rigid structure due to the presence of these phenyl groups, which can affect its physical and chemical properties. It is typically used in the synthesis of various polymers and as a building block in the creation of more complex organic molecules. The tetraphenyl-adipic acid's unique structure also makes it a subject of interest in materials science, particularly in the development of new materials with specific optical, electronic, or mechanical properties.
The CAS Registry Mumber 28019-91-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,0,1 and 9 respectively; the second part has 2 digits, 9 and 1 respectively. Calculate Digit Verification of CAS Registry Number 28019-91: (7*2)+(6*8)+(5*0)+(4*1)+(3*9)+(2*9)+(1*1)=112 112 % 10 = 2 So 28019-91-2 is a valid CAS Registry Number.
