Methoxydifluorophosphine, also known as phosphorus oxydifluoride or phosphorus(V) oxydifluoride, is a chemical compound with the formula (CH3O)PF2. It is a colorless, volatile, and highly toxic liquid that is sensitive to moisture and light. methoxydifluorophosphine is an important intermediate in the production of various organophosphorus compounds, such as pesticides and flame retardants. Methoxydifluorophosphine is synthesized by reacting phosphorus trifluoride (PF3) with methanol (CH3OH) and is used as a reagent in the synthesis of other phosphorus-containing compounds. Due to its high reactivity and toxicity, it requires careful handling and storage.
The CAS Registry Mumber 381-65-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,8 and 1 respectively; the second part has 2 digits, 6 and 5 respectively. Calculate Digit Verification of CAS Registry Number 381-65: (5*3)+(4*8)+(3*1)+(2*6)+(1*5)=67 67 % 10 = 7 So 381-65-7 is a valid CAS Registry Number.
