1H-Cyclopropa(1)phenanthrene is a polycyclic aromatic hydrocarbon (PAH) consisting of a cyclopropane ring fused to a phenanthrene molecule. This organic compound is characterized by its unique structure, which features three fused benzene rings and a cyclopropane ring, making it a highly strained molecule due to the presence of the cyclopropane ring. It is a member of the larger family of PAHs, which are known for their potential carcinogenic and mutagenic properties. 1H-Cyclopropa(1)phenanthrene is of interest in chemical research due to its unusual structure and potential applications in the synthesis of other complex organic compounds. However, due to its potential health risks, it is important to handle 1H-cyclopropa(l)phenanthrene with caution and in accordance with proper safety protocols.
The CAS Registry Mumber 278-91-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,7 and 8 respectively; the second part has 2 digits, 9 and 1 respectively. Calculate Digit Verification of CAS Registry Number 278-91: (5*2)+(4*7)+(3*8)+(2*9)+(1*1)=81 81 % 10 = 1 So 278-91-1 is a valid CAS Registry Number.
