Z-L-Pro-D-Ala-OEt, also known as N-benzyloxycarbonyl-L-prolyl-D-alanine ethyl ester, is a synthetic peptide compound consisting of three amino acids: L-proline, D-alanine, and a protecting group, N-benzyloxycarbonyl (Z). The ethyl ester (OEt) group is attached to the carboxylic acid end, making it a water-soluble derivative. Z-L-Pro-D-Ala-OEt is commonly used in peptide synthesis as a building block for the formation of larger peptide sequences, particularly in the synthesis of antibiotics and other bioactive molecules. The Z group serves as a temporary protecting group that shields the amino group during peptide bond formation, preventing unwanted side reactions, and is later removed under acidic conditions to yield the desired peptide sequence.

Check Digit Verification of cas no

The CAS Registry Mumber 98807-08-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,8,0 and 7 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 98807-08:
(7*9)+(6*8)+(5*8)+(4*0)+(3*7)+(2*0)+(1*8)=180
180 % 10 = 0
So 98807-08-0 is a valid CAS Registry Number.
