1-(2-Chlor-phenyl)-fluoranthen, also known as 1-(2-chlorophenyl)fluorene, is an organic compound with the chemical formula C17H11Cl. It is a derivative of fluorene, a polycyclic aromatic hydrocarbon, with a chlorine atom attached to the phenyl ring at the 2-position. 1-(2-Chlor-phenyl)-fluoranthen is characterized by its planar structure and conjugated π-electron system, which contributes to its stability and potential applications in various fields, such as organic synthesis and materials science. Due to the presence of the chlorine atom, it may exhibit different chemical reactivity compared to its parent compound, fluorene. However, it is important to note that the compound's specific properties, such as toxicity and environmental impact, should be considered when evaluating its suitability for various applications.
The CAS Registry Mumber 5209-02-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,0 and 9 respectively; the second part has 2 digits, 0 and 2 respectively. Calculate Digit Verification of CAS Registry Number 5209-02: (6*5)+(5*2)+(4*0)+(3*9)+(2*0)+(1*2)=69 69 % 10 = 9 So 5209-02-9 is a valid CAS Registry Number.
