N-L-Alanyl-glycin-<4-nitro-phenylester> is a chemical compound that consists of an L-alanine molecule, a glycine molecule, and a 4-nitrophenyl ester group. L-alanine and glycine are amino acids, which are the building blocks of proteins, while the 4-nitrophenyl ester group is an aromatic compound with a nitro group. N-L-Alanyl-glycin-<4-nitro-phenylester> is formed through the esterification reaction between the carboxyl group of the L-alanine and the hydroxyl group of the glycine, with the 4-nitrophenyl ester group attached to the resulting dipeptide. N-L-Alanyl-glycin-<4-nitro-phenylester> is often used in biochemical research and as a substrate for enzyme assays, particularly for studying the activity of proteases, which are enzymes that break down proteins into smaller peptides or amino acids.
The CAS Registry Mumber 1874-71-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,7 and 4 respectively; the second part has 2 digits, 7 and 1 respectively. Calculate Digit Verification of CAS Registry Number 1874-71: (6*1)+(5*8)+(4*7)+(3*4)+(2*7)+(1*1)=101 101 % 10 = 1 So 1874-71-1 is a valid CAS Registry Number.
