222-21-9 Usage
General Description
12H-[1]benzothieno[2,3-a]carbazole is a chemical compound that belongs to the family of benzothienocarbazoles, which are polycyclic aromatic compounds containing a benzothieno[2,3-a]carbazole moiety. The exact properties and potential applications of this specific compound are not extensively studied or reported in literature, which suggests its relative obscurity in scientific research. As a polycyclic aromatic compound, it could potentially exhibit characteristics like fluorescence, intercalation with other substances, or act as a precursor to other compounds, all of which are properties commonly associated with compounds of this family. However, these potential properties or uses have not been confirmed for 12H-[1]benzothieno[2,3-a]carbazole specifically. Note that handling such compound should be done carefully due to probable associated health risks from handling polycyclic aromatic compounds.
Check Digit Verification of cas no
The CAS Registry Mumber 222-21-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,2 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 222-21:
(5*2)+(4*2)+(3*2)+(2*2)+(1*1)=29
29 % 10 = 9
So 222-21-9 is a valid CAS Registry Number.

A Br?nsted acid catalyzed cascade benzannulation strategy for the one-pot synthesis of densely populated poly-aryl benzo[a]carbazole architectures is disclosed from easily affordable fundamental commodities. The efficacy of this technique was further validated via the concise synthesis of structurally unique carbazole based poly-aromatic hydrocarbons. Furthermore, the photo-physical properties of the synthesized compounds are thoroughly investigated.
