1,2,2,2-Tetrafluoroethylsulfonyl fluoride, also known as TESF, is a chemical compound with the molecular formula C2F5SO2F. It is a colorless, odorless, and highly reactive liquid with a molecular weight of 174.06 g/mol. TESF is commonly used as a fluorination reagent in organic synthesis, particularly in the preparation of fluorinated compounds. It is also utilized as a building block for the synthesis of pharmaceuticals, agrochemicals, and other fine chemicals. TESF is highly toxic and requires careful handling and proper safety measures to prevent exposure.
Check Digit Verification of cas no
The CAS Registry Mumber 2127-74-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,2 and 7 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2127-74:
(6*2)+(5*1)+(4*2)+(3*7)+(2*7)+(1*4)=64
64 % 10 = 4
So 2127-74-4 is a valid CAS Registry Number.
