The chemical sequence "Tyr(Me)-Phe-Val-Asn-Cys(Bzl)-Pro-D-Arg(Tos)-Gly-NH2" represents a peptide, which is a short chain of amino acids linked by peptide bonds. This particular peptide is composed of the following amino acids: Tyrosine with a methyl group (Tyr(Me)), Phenylalanine (Phe), Valine (Val), Asparagine (Asn), Cysteine with a benzyl group (Cys(Bzl)), Proline (Pro), D-arginine with a tosyl group (D-Arg(Tos)), and Glycine (Gly), with an amino group at the end (NH2). The presence of D-arginine indicates that it is a non-natural amino acid, as it is the mirror image of the naturally occurring L-arginine. The benzyl and tosyl groups are protecting groups used in peptide synthesis to prevent unwanted side reactions. This peptide sequence is likely to be of interest in the field of biochemistry or pharmaceuticals, possibly as a component of a drug or a model for studying protein interactions.

Check Digit Verification of cas no

The CAS Registry Mumber 84891-11-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,8,9 and 1 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 84891-11:
(7*8)+(6*4)+(5*8)+(4*9)+(3*1)+(2*1)+(1*1)=162
162 % 10 = 2
So 84891-11-2 is a valid CAS Registry Number.
