Trifluoro-methanethiol anion, also known as trifluoromethylthiolate or CF3S?, is a chemical species derived from trifluoromethanethiol (CF3SH), where the hydrogen atom is replaced by a negatively charged sulfur atom. This anion is a key intermediate in various chemical reactions and synthesis processes, particularly in the production of pharmaceuticals, agrochemicals, and other specialty chemicals. It is characterized by its strong electron-withdrawing trifluoromethyl group, which influences its reactivity and stability. Trifluoro-methanethiol anion is also known for its unique properties, such as its ability to form stable complexes with transition metals, making it a valuable building block in organometallic chemistry.
The CAS Registry Mumber 83193-05-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,1,9 and 3 respectively; the second part has 2 digits, 0 and 5 respectively. Calculate Digit Verification of CAS Registry Number 83193-05: (7*8)+(6*3)+(5*1)+(4*9)+(3*3)+(2*0)+(1*5)=129 129 % 10 = 9 So 83193-05-9 is a valid CAS Registry Number.
