1,1,2,2-Tetrachloro-3,3-difluorocyclobutane is a chlorofluorocarbon (CFC) with the chemical formula C4Cl4F2. It is a colorless, volatile liquid at room temperature and is known for its high stability and low reactivity. 1,1,2,2-tetrachloro-3,3-difluorocyclobutane is a derivative of cyclobutane, where two hydrogen atoms are replaced by fluorine atoms, and two hydrogen atoms are replaced by chlorine atoms. Due to its chemical structure, it has been used as a refrigerant, a propellant in aerosol products, and as a solvent. However, it is also a potent greenhouse gas and contributes to the depletion of the ozone layer, which has led to its phase-out in many applications under international agreements like the Montreal Protocol. The compound's environmental impact and potential health risks have made it a subject of concern, and efforts are ongoing to find and use more environmentally friendly alternatives.

697-16-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 697-16-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,9 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 697-16:
(5*6)+(4*9)+(3*7)+(2*1)+(1*6)=95
95 % 10 = 5
So 697-16-5 is a valid CAS Registry Number.
