4-(1-Pentylhexyl)-phenol, also known as Octylphenol, is a synthetic organic compound with the chemical formula C24H40O. It is a derivative of phenol, characterized by an octyl chain (a hydrocarbon chain with eight carbon atoms) attached to the para position of the phenol ring. 4-(1-Pentylhexyl)-phenol is primarily used as a nonionic surfactant, emulsifier, and stabilizer in various industrial applications, including the manufacturing of polymers, resins, and detergents. Due to its potential environmental and health concerns, its use has been restricted in some regions.
The CAS Registry Mumber 6465-72-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,6 and 5 respectively; the second part has 2 digits, 7 and 2 respectively. Calculate Digit Verification of CAS Registry Number 6465-72: (6*6)+(5*4)+(4*6)+(3*5)+(2*7)+(1*2)=111 111 % 10 = 1 So 6465-72-1 is a valid CAS Registry Number.
