N,N-Diethylamidosulfonyl fluoride, also known as DEF or Deethylaminosulfonyl fluoride, is a potent and irreversible serine protease inhibitor. It is an organosulfur compound with the chemical formula C4H10FNO2S. DEF is widely used in biochemical research to study the function and activity of serine proteases, which are a class of enzymes that play crucial roles in various biological processes, including blood clotting, digestion, and the immune response. By covalently binding to the active site of serine proteases, DEF inhibits their activity, allowing researchers to investigate the specific roles these enzymes play in different systems. Due to its high reactivity and potential toxicity, DEF must be handled with care and used in controlled laboratory settings.

382-97-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 382-97-8 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 2 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 382-97:
(5*3)+(4*8)+(3*2)+(2*9)+(1*7)=78
78 % 10 = 8
So 382-97-8 is a valid CAS Registry Number.
