98791-45-8 Usage
General Description
1,2,6,7-Tetrahydrodicyclopenta[cd,jk]pyrene is a polycyclic aromatic hydrocarbon (PAH) that is a byproduct of incomplete combustion processes, such as those found in cigarette smoke, automobile exhaust, and industrial emissions. It is a highly carcinogenic compound and has been classified as a Group 1 carcinogen by the International Agency for Research on Cancer (IARC). Exposure to this chemical has been linked to an increased risk of lung cancer, as well as other respiratory and cardiovascular diseases. Additionally, it has been shown to have mutagenic and genotoxic effects, leading to DNA damage and potential long-term health problems. Due to its harmful effects, efforts are being made to reduce human exposure to 1,2,6,7-Tetrahydrodicyclopenta[cd,jk]pyrene through regulations and pollution control measures.
Check Digit Verification of cas no
The CAS Registry Mumber 98791-45-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,7,9 and 1 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 98791-45:
(7*9)+(6*8)+(5*7)+(4*9)+(3*1)+(2*4)+(1*5)=198
198 % 10 = 8
So 98791-45-8 is a valid CAS Registry Number.

Organic compound containing condensed ring structure and organic electroluminescent device
-
, (2020/05/02)
The invention provides an organic compound containing a condensed ring structure as shown in a formula I which is described in the specification. The invention also provides an application of the organic compound in an electroluminescent device. Compared with organic compounds in the prior art, the organic compound containing the condensed ring structure has a narrower half-peak width of an emission peak, so that the organic compound has excellent color purity; when the organic compound containing the condensed ring structure is applied to an AMOLED top emission screen body, higher luminous efficiency can be achieved, and an organic light-emitting device can have lower driving voltage and longer service lifetime.
