"Z-D-Val-L-HyIv-L-Ala-D-HyIv" is a peptide sequence consisting of seven amino acids. The sequence starts with Z-D-Val, where Z is a protecting group, D-Val is the D-isomer of valine, an amino acid. Next is L-HyIv, which is the L-isomer of hydroxyisoleucine, another amino acid. This is followed by L-Ala, the L-isomer of alanine, a simple amino acid. The sequence ends with D-HyIv, the D-isomer of hydroxyisoleucine. This specific arrangement of amino acids, with their respective isomers and a protecting group, suggests a tailored peptide with potential applications in research or pharmaceuticals, possibly for studying protein interactions or as a component in drug design.

Check Digit Verification of cas no

The CAS Registry Mumber 31508-99-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,5,0 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 31508-99:
(7*3)+(6*1)+(5*5)+(4*0)+(3*8)+(2*9)+(1*9)=103
103 % 10 = 3
So 31508-99-3 is a valid CAS Registry Number.
