α,α'-Bis-(1,2-dichlor-tetrafluor-cyclobutyl)-diaethylaether, also known as octafluorocyclo-1,2-butane, is a chemical compound with the molecular formula C8Cl2F8O2. It is a colorless liquid at room temperature and is characterized by its symmetrical structure, featuring two 1,2-dichlorotetrafluoro-cyclobutyl groups connected by an ethyl ether bridge. α,α'-Bis-(1,2-dichlor-tetrafluor-cyclobutyl)-diaethylaether is known for its high thermal stability and chemical inertness, which makes it useful in various industrial applications, such as a heat transfer fluid and a dielectric fluid in electrical equipment. Due to its nonflammable nature and low toxicity, it is also considered a safer alternative to some traditional chemicals used in these applications. However, it is important to handle this substance with care, as it can still pose health risks if not managed properly, and it is subject to specific regulations regarding its use and disposal.
The CAS Registry Mumber 904-82-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,0 and 4 respectively; the second part has 2 digits, 8 and 2 respectively. Calculate Digit Verification of CAS Registry Number 904-82: (5*9)+(4*0)+(3*4)+(2*8)+(1*2)=75 75 % 10 = 5 So 904-82-5 is a valid CAS Registry Number.
