[4.4]Paracyclophane is a cyclic organic compound consisting of eight carbon atoms arranged in a parallelogram-like structure, with four carbon atoms forming each parallel side. It is a member of the paracyclophane family, which are characterized by their cyclic nature and the presence of two benzene rings connected by methylene bridges. The compound is known for its unique molecular geometry, which results in a strained conformation due to the close proximity of the two benzene rings. This strain leads to interesting chemical and physical properties, such as a high degree of rigidity and unique electronic interactions between the aromatic rings. [4.4]Paracyclophane has been studied for its potential applications in various fields, including materials science, supramolecular chemistry, and as a model for understanding the behavior of more complex cyclic systems.
The CAS Registry Mumber 502-08-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,0 and 2 respectively; the second part has 2 digits, 0 and 8 respectively. Calculate Digit Verification of CAS Registry Number 502-08: (5*5)+(4*0)+(3*2)+(2*0)+(1*8)=39 39 % 10 = 9 So 502-08-9 is a valid CAS Registry Number.
