Z-ALA-PRO-GLY-OH, also known as Carbobenzoxy-L-alanine-L-proline-glycine, is a peptide compound consisting of three amino acids: L-alanine, L-proline, and glycine. The "Z" group, or carbobenzoxy group, is a protecting group used in peptide synthesis to prevent unwanted side reactions. This specific sequence of amino acids is of interest in the field of medicinal chemistry, as it can be a precursor to the synthesis of various bioactive peptides and has potential applications in drug development. The compound is also used as a substrate in enzyme assays to study the activity of proteases, which are enzymes that break down proteins.
The CAS Registry Mumber 23458-25-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,4,5 and 8 respectively; the second part has 2 digits, 2 and 5 respectively. Calculate Digit Verification of CAS Registry Number 23458-25: (7*2)+(6*3)+(5*4)+(4*5)+(3*8)+(2*2)+(1*5)=105 105 % 10 = 5 So 23458-25-5 is a valid CAS Registry Number.
