Pentafluorothiodifluoromethyl-trifluoromethylsulfurtetrafluoride, also known as sulfur hexafluoride (SF6), is a colorless, odorless, non-toxic, and non-flammable gas. It is composed of one sulfur atom and six fluorine atoms, with a molecular formula of SF6. This chemical is highly stable and has a strong electronegativity, making it an excellent insulator and dielectric material. It is widely used in the electrical industry, particularly in high-voltage switchgear and transformers, due to its ability to prevent electrical arcing and reduce power loss. Additionally, SF6 has applications in the semiconductor industry, as a tracer gas for leak detection, and in the medical field for magnetic resonance imaging (MRI). However, it is important to note that SF6 is a potent greenhouse gas with a global warming potential much higher than that of carbon dioxide, which necessitates careful handling and management to minimize its environmental impact.
The CAS Registry Mumber 1543-46-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,4 and 3 respectively; the second part has 2 digits, 4 and 6 respectively. Calculate Digit Verification of CAS Registry Number 1543-46: (6*1)+(5*5)+(4*4)+(3*3)+(2*4)+(1*6)=70 70 % 10 = 0 So 1543-46-0 is a valid CAS Registry Number.
