109881-52-9 Usage
General Description
2,3,7,8-Tetramethoxydibenzofuran (TETRO) is a chemical compound that belongs to the dibenzofuran family. It is a colorless solid with a molecular formula of C14H14O5. TETRO is considered a dioxin and is a byproduct of some industrial processes, such as waste incineration and certain chemical manufacturing. It is also found in small amounts in the environment as a result of natural processes. TETRO is considered to be a persistent organic pollutant and poses potential risks to human health and the environment, as it is known to be toxic and can bioaccumulate in food chains. Studies have also shown that TETRO exposure can have adverse effects on reproductive and developmental systems in animals. Due to its toxic nature, TETRO is regulated and monitored by environmental agencies to minimize its impact on human and environmental health.
Check Digit Verification of cas no
The CAS Registry Mumber 109881-52-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,8,8 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 109881-52:
(8*1)+(7*0)+(6*9)+(5*8)+(4*8)+(3*1)+(2*5)+(1*2)=149
149 % 10 = 9
So 109881-52-9 is a valid CAS Registry Number.

Versatile oxidative approach to carbazoles and related compounds using MoCl5
Trosien, Simon,B?ttger, Philipp,Waldvogel, Siegfried R.
, p. 402 - 405 (2014/04/03)
The unique oxidizing power of molybdenum pentachloride provides an easy to perform, versatile, and high yielding method to construct carbazoles and the corresponding dibenzo analogues of thiophene, furan, and selenophene. The coupling reaction tolerates a variety of functional groups. The synthesis is highly modular. By this approach a precursor for the naturally occurring carbazole koenigicine was prepared.
