The chemical sequence "Z-D-Val-D-Lac-L-Val-L-HyIv-D-Val-D-Lac-L-Val-L-HyIv" represents a peptide composed of various amino acids. The sequence starts with a Z group, which is likely a protecting group used in peptide synthesis. It is followed by a D-valine (D-Val), a D-lactic acid (D-Lac), and an L-valine (L-Val). The sequence then includes L-hydroxyisovaleric acid (L-HyIv), which is a non-proteinogenic amino acid. The peptide is symmetrical, with the second half being a mirror image of the first half, ending with another L-HyIv. This specific arrangement of amino acids and the inclusion of a non-proteinogenic acid suggest that this peptide may have unique properties or functions, potentially in a biological or pharmaceutical context. The exact role or application of this peptide would depend on the specific context in which it is used, and further research would be needed to understand its full implications.

Check Digit Verification of cas no

The CAS Registry Mumber 13509-22-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,5,0 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 13509-22:
(7*1)+(6*3)+(5*5)+(4*0)+(3*9)+(2*2)+(1*2)=83
83 % 10 = 3
So 13509-22-3 is a valid CAS Registry Number.
