Triethyldifluorophosphorane, also known as phosphorus trifluoride diethyl etherate or (EtO)3PF2, is an organophosphorus compound that serves as a valuable reagent in organic synthesis. It is a colorless, volatile liquid with a pungent odor and is highly sensitive to moisture and air. Triethyldifluorophosphorane is primarily used as a fluorinating agent, particularly in the conversion of alcohols to alkyl fluorides, and as a source of the difluorophosphorane anion (PF2-) in various chemical reactions. Due to its reactivity and potential hazards, it is essential to handle triethyldifluorophosphorane with caution and in an appropriate laboratory setting.

Check Digit Verification of cas no

The CAS Registry Mumber 677-11-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,7 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 677-11:
(5*6)+(4*7)+(3*7)+(2*1)+(1*1)=82
82 % 10 = 2
So 677-11-2 is a valid CAS Registry Number.
