The chemical sequence "Z(OMe)-Cys(MBzl)-Lys(Z)-Asn-Gly-NHNH-Troc" represents a peptide with specific modifications. The peptide is composed of six amino acids: Cysteine (Cys), Lysine (Lys), Asparagine (Asn), and Glycine (Gly), with two additional chemical groups attached to certain amino acids. The "Z(OMe)" group is a protecting group for the thiol group of cysteine, which is crucial for preventing unwanted side reactions during peptide synthesis. The "MBzl" group is a protecting group for the amino group of lysine, which helps in controlling the reactivity of the amino group. The "Z" group is another protecting group, this time for the amino group of lysine, ensuring that the peptide chain grows in a controlled manner. The "NHNH" part indicates a free amino group at the end of the peptide, which is essential for further reactions or modifications. Lastly, the "Troc" group is a protecting group for the amino group of the terminal amino acid, which is important for the stability of the peptide during synthesis. This sequence is a complex peptide with specific protective groups that are used in the synthesis process to ensure the correct formation and reactivity of the peptide chain.

Check Digit Verification of cas no

The CAS Registry Mumber 76224-12-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,2,2 and 4 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 76224-12:
(7*7)+(6*6)+(5*2)+(4*2)+(3*4)+(2*1)+(1*2)=119
119 % 10 = 9
So 76224-12-9 is a valid CAS Registry Number.
