196-28-1 Usage
General Description
Dibenzo[c,mno]chrysene, also known as dibenzo[a,l]pyrene, is a polycyclic aromatic hydrocarbon (PAH) with a chemical structure consisting of five benzene rings fused together. It is a highly carcinogenic and mutagenic compound that is formed as a byproduct of incomplete combustion of organic materials, such as tobacco smoke, diesel exhaust, and charbroiled foods. Dibenzo[c,mno]chrysene is classified as a Group 2A carcinogen by the International Agency for Research on Cancer (IARC), meaning that it is likely to cause cancer in humans. It is also an environmental pollutant and has been found to persist in soil, water, and air, posing a significant health risk to both humans and wildlife. Due to its harmful effects, efforts are being made to reduce human exposure to dibenzo[c,mno]chrysene and other PAHs.
Check Digit Verification of cas no
The CAS Registry Mumber 196-28-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,9 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 196-28:
(5*1)+(4*9)+(3*6)+(2*2)+(1*8)=71
71 % 10 = 1
So 196-28-1 is a valid CAS Registry Number.

A convenient and general synthesis of cata- and peri-condensed polycyclic aromatic hydrocarbons with a Fjord-region
Kumar, Subodh
, p. 841 - 844 (2007/10/03)
Cata- and peri-condensed polycyclic aromatic hydrocarbons (PAHs) 10a-d and 11 have been conveniently synthesized by the application of Suzuki cross-coupling reaction. In three to four steps, these PAHs having fjord-region were obtained in an overall yield of 35-51% from commercially or easily accessible aryl boronic acids and aryl bromides.
