Z-Asn-Pro-Ala-OtBu is a peptide compound consisting of four amino acids: asparagine (Asn), proline (Pro), and alanine (Ala), with a tert-butyloxycarbonyl (OtBu) group attached to the N-terminus. This specific sequence of amino acids is protected by the Z group (benzyloxycarbonyl), which is a common protecting group used in peptide synthesis to prevent unwanted side reactions. The OtBu group is a bulky protecting group that shields the carboxylic acid group, allowing for selective deprotection and coupling reactions in peptide synthesis. Z-Asn-Pro-Ala-OtBu is a valuable intermediate in the synthesis of larger peptides and proteins, as it can be further elongated by adding more amino acids to form longer sequences.

Check Digit Verification of cas no

The CAS Registry Mumber 75141-63-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,1,4 and 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 75141-63:
(7*7)+(6*5)+(5*1)+(4*4)+(3*1)+(2*6)+(1*3)=118
118 % 10 = 8
So 75141-63-8 is a valid CAS Registry Number.
