"Z-D-Ala-D-HyIv-L-Val-L-HyIv-D-Ala-D-HyIv-L-Val-L-HyIv-OtBu" is a complex peptide sequence consisting of multiple amino acids and a protecting group. The sequence is characterized by the presence of D-alanine (D-Ala), D-hydroisovaline (D-HyIv), L-valine (L-Val), and L-hydroisovaline (L-HyIv) in an alternating pattern, with a Z-group (benzyloxycarbonyl) protecting the N-terminus and an OtBu (tert-butyloxycarbonyl) protecting the C-terminus. This specific arrangement of amino acids and protecting groups suggests that the peptide may have unique properties and potential applications in various fields, such as pharmaceuticals or chemical research.

Check Digit Verification of cas no

The CAS Registry Mumber 31508-91-5 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 1 respectively.
Calculate Digit Verification of CAS Registry Number 31508-91:
(7*3)+(6*1)+(5*5)+(4*0)+(3*8)+(2*9)+(1*1)=95
95 % 10 = 5
So 31508-91-5 is a valid CAS Registry Number.
