Silicon fluoride, also known as hexafluorosilicic acid (H2SiF6), is a colorless, odorless, and highly corrosive chemical compound. It is formed when silicon tetrafluoride (SiF4) reacts with water, and it is commonly used in the production of various silicon-based materials, such as optical fibers and semiconductors. Silicon fluoride is also employed in the fluoridation of water supplies to help prevent dental caries. Due to its corrosive nature and potential health risks, it is essential to handle and store silicon fluoride with proper safety measures and precautions.
The CAS Registry Mumber 393-84-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,9 and 3 respectively; the second part has 2 digits, 8 and 4 respectively. Calculate Digit Verification of CAS Registry Number 393-84: (5*3)+(4*9)+(3*3)+(2*8)+(1*4)=80 80 % 10 = 0 So 393-84-0 is a valid CAS Registry Number.
