"Z(OMe)-Asn-Lys(Z)-Ala-OMe" is a peptide sequence consisting of four amino acids: Asparagine (Asn), Lysine (Lys), and Alanine (Ala), with two protecting groups, Z(OMe) and Z, attached to the N-terminus and the side chain of Lysine, respectively. The Z(OMe) group is a benzyloxycarbonyl (Cbz) protecting group with a methoxyethyl (OMe) substituent, while the Z group is another benzyloxycarbonyl protecting group. These protecting groups are crucial in peptide synthesis to prevent unwanted side reactions and ensure the correct formation of peptide bonds. The sequence is capped with a methoxy group (OMe) at the C-terminus, which also serves as a protecting group. This specific peptide sequence is often used in the synthesis of larger peptides and proteins, with the protecting groups being removed at appropriate stages to facilitate further reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 80503-71-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,5,0 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 80503-71:
(7*8)+(6*0)+(5*5)+(4*0)+(3*3)+(2*7)+(1*1)=105
105 % 10 = 5
So 80503-71-5 is a valid CAS Registry Number.
