The chemical sequence "Z-Pyr-Leu-His-Val-Asn-Lys(Z)-Ala-Arg(Mts)-Arg(Mts)-Pro-Tyr-Ile-Leu-OBzl" represents a peptide, which is a chain of amino acids. In this specific peptide, several amino acids are present, including pyroglutamic acid (Pyr), leucine (Leu), histidine (His), valine (Val), asparagine (Asn), lysine (Lys), alanine (Ala), arginine (Arg), proline (Pro), tyrosine (Tyr), isoleucine (Ile), and leucine (Leu) again. Notably, lysine is modified with a benzyloxycarbonyl (Z) group, and two arginines are modified with a 4-methyltrityl (Mts) group. The peptide is capped with an obzl group, which is likely a benzyl ester protecting group. This sequence is of interest in biochemistry and pharmaceuticals, potentially for its specific biological activity or as a component in drug design.

Check Digit Verification of cas no

The CAS Registry Mumber 80503-78-2 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 8 respectively.
Calculate Digit Verification of CAS Registry Number 80503-78:
(7*8)+(6*0)+(5*5)+(4*0)+(3*3)+(2*7)+(1*8)=112
112 % 10 = 2
So 80503-78-2 is a valid CAS Registry Number.
