8-(o-Toluyl)-1,2;4,5-dibenzo-pyren is a complex organic compound with the molecular formula C28H18. It is a derivative of pyrene, a polycyclic aromatic hydrocarbon (PAH) consisting of five fused benzene rings. The compound is characterized by the presence of an o-tolyl group (a methyl group attached to an ortho position of a benzene ring) at the 8th position and two additional benzene rings fused to the 1,2 and 4,5 positions of the pyrene core. This chemical is of interest in the field of organic chemistry and may have potential applications in materials science and pharmaceutical research. However, due to its complex structure and potential carcinogenic properties associated with PAHs, further studies are required to understand its full implications and safety profile.
The CAS Registry Mumber 2950-29-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,5 and 0 respectively; the second part has 2 digits, 2 and 9 respectively. Calculate Digit Verification of CAS Registry Number 2950-29: (6*2)+(5*9)+(4*5)+(3*0)+(2*2)+(1*9)=90 90 % 10 = 0 So 2950-29-0 is a valid CAS Registry Number.
