α,2,3,4,5,6-Hexafluorostyrol, also known as 2,3,4,5,6-hexafluorostyrene or 2,3,4,5,6-pentafluorophenyl vinyl ether, is a synthetic chemical compound with the molecular formula C8H3F5. It is a colorless liquid with a pungent odor and is used as an intermediate in the production of various fluorinated compounds, such as pharmaceuticals, agrochemicals, and specialty materials. Due to its highly reactive nature, it is essential to handle Hexafluorostyrol with proper safety measures, including the use of personal protective equipment and controlled environments.
The CAS Registry Mumber 54635-81-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,6,3 and 5 respectively; the second part has 2 digits, 8 and 1 respectively. Calculate Digit Verification of CAS Registry Number 54635-81: (7*5)+(6*4)+(5*6)+(4*3)+(3*5)+(2*8)+(1*1)=133 133 % 10 = 3 So 54635-81-3 is a valid CAS Registry Number.
