Bis(heptafluor-n-propyl)-chlorphosphan, also known as chloropentafluoropropane or CHF2CF2CF3, is a colorless, volatile liquid with a molecular formula of C3ClF7P. It is a derivative of phosphorus and belongs to the class of organophosphorus compounds. This chemical is primarily used as a refrigerant, fire extinguishing agent, and blowing agent in various industrial applications. Due to its high stability, low toxicity, and non-flammability, it has gained popularity as a safer alternative to other chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) in the refrigeration and air conditioning sectors. However, it is essential to handle and store this chemical with care, as it can cause irritation to the eyes, skin, and respiratory system if inhaled or absorbed through the skin.
The CAS Registry Mumber 756-17-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,5 and 6 respectively; the second part has 2 digits, 1 and 7 respectively. Calculate Digit Verification of CAS Registry Number 756-17: (5*7)+(4*5)+(3*6)+(2*1)+(1*7)=82 82 % 10 = 2 So 756-17-2 is a valid CAS Registry Number.
