6525-37-7 Usage
General Description
2,3-Dihydro-2,3-dimethyl-benzo[b]thiophene 1,1-dioxide, also known as dibenzothiophene dioxide, is a heterocyclic organic compound with the molecular formula C10H10O2S. It is commonly found in crude oil and coal tar and is often targeted for removal due to its negative effects on the environment and human health. Dibenzothiophene dioxide is known for its strong odor and is a common component in the formation of sulfuric acid during the combustion of fossil fuels. It is also used in the production of pharmaceuticals and agrochemicals. Additionally, it is considered a potential environmental contaminant and is regulated as a priority pollutant by the US Environmental Protection Agency.
Check Digit Verification of cas no
The CAS Registry Mumber 6525-37-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,2 and 5 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6525-37:
(6*6)+(5*5)+(4*2)+(3*5)+(2*3)+(1*7)=97
97 % 10 = 7
So 6525-37-7 is a valid CAS Registry Number.

Iridium-Catalyzed Asymmetric Hydrogenation of Benzo[b]thiophene 1,1-Dioxides
Tosatti, Paolo,Pfaltz, Andreas
, p. 4579 - 4582 (2017)
An efficient iridium-catalyzed asymmetric hydrogenation of substituted benzothiophene 1,1-dioxides is described. The use of iridium complexes with chiral pyridyl phosphinite ligands provides access to highly enantiomerically enriched sulfones with substituents at the 2- and 3-position. Sulfones of this type are of interest as core structures of agrochemicals and pharmaceuticals. Moreover, they can be further reduced to chiral 2,3-dihydrobenzothiophenes.
