6297-58-1 Usage
General Description
Nα-phenylmethanesulfonyl-DL-tryptophan, also known as PMSF-tryptophan, is a chemical compound that is commonly used as a protease inhibitor in biochemical and molecular biology research. It is a derivative of the amino acid tryptophan and contains a sulfonyl group which makes it an effective inhibitor of serine proteases. PMSF-tryptophan is often used to prevent the degradation of proteins by proteases during purification and analysis. It works by irreversibly binding to the active site of serine proteases, thereby inhibiting their activity. Nα-phenylmethanesulfonyl-DL-tryptophan has been widely used in a variety of research studies and is an important tool for the study of protease function and regulation.
Check Digit Verification of cas no
The CAS Registry Mumber 6297-58-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,9 and 7 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6297-58:
(6*6)+(5*2)+(4*9)+(3*7)+(2*5)+(1*8)=121
121 % 10 = 1
So 6297-58-1 is a valid CAS Registry Number.
