Z-Arg(Tos)-Leu-Gln-Arg(Tos)-Leu-OH is a synthetic peptide composed of six amino acids, with a molecular weight of approximately 1,000 Da. The sequence features two Arginine (Arg) residues, which are modified with a tosyl group (Tos), two Leucine (Leu) residues, and one Glutamine (Gln) residue. The peptide is capped with a hydroxyl group (OH) at the C-terminus. This specific arrangement of amino acids and modifications may confer unique properties to the peptide, such as stability, solubility, or biological activity, depending on its intended application. The tosyl group is often used to protect the guanidinium group of arginine, which can be crucial in certain chemical reactions or to prevent unwanted side reactions. The peptide's structure and composition make it a potential candidate for various applications in research, drug development, or as a component in biochemical assays.

Check Digit Verification of cas no

The CAS Registry Mumber 83077-80-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,0,7 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 83077-80:
(7*8)+(6*3)+(5*0)+(4*7)+(3*7)+(2*8)+(1*0)=139
139 % 10 = 9
So 83077-80-9 is a valid CAS Registry Number.
