1-Nitro-3-(1,1,2,2-tetrafluor-aethyl-mercapto)-benzol is a complex organic compound characterized by its molecular formula C9H6F4NO2S. 1-Nitro-3-(1,1,2,2-tetrafluor-aethyl-mercapto)-benzol features a benzene ring with a nitro group at the 1-position and a tetrafluoroethylmercapto group at the 3-position. The tetrafluoroethylmercapto group consists of a sulfur atom bonded to a tetrafluoroethyl group, which is an ethyl group with all hydrogen atoms replaced by fluorine atoms. This chemical is known for its unique properties, such as its reactivity and potential applications in the synthesis of various pharmaceuticals and specialty chemicals. Due to the presence of fluorine atoms, it may exhibit different chemical behaviors compared to its non-fluorinated counterparts, making it a subject of interest in fluorochemistry.
The CAS Registry Mumber 1644-20-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,4 and 4 respectively; the second part has 2 digits, 2 and 0 respectively. Calculate Digit Verification of CAS Registry Number 1644-20: (6*1)+(5*6)+(4*4)+(3*4)+(2*2)+(1*0)=68 68 % 10 = 8 So 1644-20-8 is a valid CAS Registry Number.
