Tetraphenylene, also known as 1,2,4,5-tetraphenylene, is an organic compound consisting of a central ring structure with four phenyl groups attached to it. It is a polycyclic aromatic hydrocarbon (PAH) with the molecular formula C28H18. Tetraphenylene is characterized by its planar structure and high symmetry, which makes it an interesting subject for research in the fields of materials science and chemistry. It has potential applications in the development of organic semiconductors, optoelectronic devices, and other advanced materials due to its unique electronic and optical properties. However, like other PAHs, tetraphenylene may also exhibit toxic and carcinogenic effects, necessitating careful handling and further research into its safety and environmental impact.
The CAS Registry Mumber 7234-88-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,3 and 4 respectively; the second part has 2 digits, 8 and 8 respectively. Calculate Digit Verification of CAS Registry Number 7234-88: (6*7)+(5*2)+(4*3)+(3*4)+(2*8)+(1*8)=100 100 % 10 = 0 So 7234-88-0 is a valid CAS Registry Number.
