Fluoroethynylsodium, also known as sodium fluoroethynide, is an inorganic compound with the chemical formula C2NaF. It is a highly reactive organometallic compound, consisting of a sodium atom bonded to a fluorine atom and an ethynyl group (C≡CH). Due to its reactivity, it is typically stored and handled under an inert atmosphere or in a vacuum to prevent unwanted reactions. Fluoroethynylsodium is used as a reagent in organic synthesis, particularly in the preparation of fluorinated organic compounds, and has potential applications in the pharmaceutical and chemical industries. However, its use requires careful handling due to its sensitivity to air, moisture, and other reactive substances.

Check Digit Verification of cas no

The CAS Registry Mumber 690-01-7 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 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 690-01:
(5*6)+(4*9)+(3*0)+(2*0)+(1*1)=67
67 % 10 = 7
So 690-01-7 is a valid CAS Registry Number.
