"Z-Arg(Mds)-Arg(Mds)-Ile-Arg(Mds)-Pro-OBut" is a synthetic peptide composed of seven amino acid residues. The sequence starts with a Z group, which is a protecting group used in peptide synthesis to prevent unwanted side reactions. The peptide contains three instances of Arg(Mds), which is an arginine residue with a 4-methylbenzenesulfonyl (Mds) protecting group. This group is used to protect the guanidinium group of arginine during peptide synthesis. The sequence also includes isoleucine (Ile) and proline (Pro), which are common amino acids found in proteins. The peptide ends with an OBut group, which is a butyl ester protecting group, used to protect the carboxyl group of the terminal amino acid. This peptide is likely used in research or pharmaceutical development, where the protecting groups are crucial for controlling the reactivity of specific functional groups during synthesis.

Check Digit Verification of cas no

The CAS Registry Mumber 80220-18-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,2,2 and 0 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 80220-18:
(7*8)+(6*0)+(5*2)+(4*2)+(3*0)+(2*1)+(1*8)=84
84 % 10 = 4
So 80220-18-4 is a valid CAS Registry Number.
