"Z(OMe)-Arg(Mts)-Lys(Z)-Lys(Z)-Leu-NHNH2" is a complex peptide sequence consisting of six amino acids. The sequence starts with Z(OMe)-Arg, where Z(OMe) represents a benzyloxycarbonyl group attached to the arginine (Arg) amino acid, protecting its side chain. This is followed by Mts-Lys, where Mts stands for 4-methyltrityl, a protecting group for the lysine (Lys) amino acid. The sequence continues with two more Z-protected lysine residues, indicating the presence of two additional lysines with their side chains protected by benzyloxycarbonyl groups. The peptide ends with a leucine (Leu) residue and a terminal NHNH2 group, which suggests the presence of a free amine group at the C-terminus, capable of forming a peptide bond with another molecule. This peptide is likely used in synthetic organic chemistry, particularly in the synthesis of larger peptides or proteins, where the protecting groups are crucial for controlling the reactivity of specific functional groups during the assembly process.

Check Digit Verification of cas no

The CAS Registry Mumber 78221-49-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,2,2 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 78221-49:
(7*7)+(6*8)+(5*2)+(4*2)+(3*1)+(2*4)+(1*9)=135
135 % 10 = 5
So 78221-49-5 is a valid CAS Registry Number.
