NPS-Ala-Gly-OH, also known as 2-(4-Nitrophenyl)sulfenyl-alanine-glycine, is a synthetic peptide consisting of two amino acids, alanine and glycine, connected by a peptide bond. The molecule features a 4-nitrophenylsulfenyl group attached to the N-terminal alanine, which is responsible for its unique chemical properties. NPS-Ala-Gly-OH is often used in biochemical research, particularly in studies involving enzyme kinetics and protein folding, due to its ability to act as a substrate for certain enzymes and its reactivity with thiols. The presence of the 4-nitrophenyl group allows for easy monitoring of reactions through changes in absorbance, making it a valuable tool in various biophysical and analytical applications.

Check Digit Verification of cas no

The CAS Registry Mumber 4635-38-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,3 and 5 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4635-38:
(6*4)+(5*6)+(4*3)+(3*5)+(2*3)+(1*8)=95
95 % 10 = 5
So 4635-38-5 is a valid CAS Registry Number.
