Z-Ala-Asn-Ser(tBu)-Asn-Pro-Ala-OH is a peptide compound consisting of seven amino acids: Z-protected alanine (Ala), asparagine (Asn), tert-butyl-protected serine (Ser(tBu)), another asparagine (Asn), proline (Pro), and alanine (Ala), with a hydroxyl group (OH) at the C-terminus. This specific sequence and protection pattern are designed to stabilize the peptide and prevent unwanted side reactions, such as hydrolysis or racemization, during synthesis or biological studies. The Z-group (benzyloxycarbonyl) is a common protecting group used in peptide synthesis to shield the N-terminal amino group, while the tert-butyl group on serine serves to protect the hydroxyl group from unwanted reactions. This particular peptide sequence may be of interest in pharmaceutical research, as it could potentially be involved in the development of drugs targeting specific biological pathways or receptors.
The CAS Registry Mumber 75141-70-7 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, 7 and 0 respectively. Calculate Digit Verification of CAS Registry Number 75141-70: (7*7)+(6*5)+(5*1)+(4*4)+(3*1)+(2*7)+(1*0)=117 117 % 10 = 7 So 75141-70-7 is a valid CAS Registry Number.
