Z-Ala-Pro-Pro-Pro-OH, also known as Z-APPPOH, is a synthetic peptide consisting of four amino acids: Z-protected alanine (Z-Ala), proline (Pro), and two additional proline residues (Pro-Pro), with a hydroxyl group (OH) at the end. This peptide is often used in research and pharmaceutical applications due to its unique structure and properties. The Z-group (benzyloxycarbonyl) is a protecting group that temporarily masks the amino group of alanine, preventing unwanted side reactions during peptide synthesis. Z-Ala-Pro-Pro-Pro-OH is of interest in the study of protein folding, enzyme substrates, and as a potential therapeutic agent in various diseases, including cancer and neurodegenerative disorders.
The CAS Registry Mumber 75893-20-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,8,9 and 3 respectively; the second part has 2 digits, 2 and 0 respectively. Calculate Digit Verification of CAS Registry Number 75893-20: (7*7)+(6*5)+(5*8)+(4*9)+(3*3)+(2*2)+(1*0)=168 168 % 10 = 8 So 75893-20-8 is a valid CAS Registry Number.
