The chemical compound in question is a complex peptide derivative, consisting of a series of amino acids linked together in a specific sequence and modified with additional functional groups. The peptide sequence starts with N-(3-benzyloxy-4-methyl-2-nitro-benzoyl)-Ls-threonine, which is a threonine amino acid with a unique benzoyl group attached. This is followed by D-valine, an isomer of the naturally occurring L-valine, and L-proline, a cyclic amino acid. The sequence continues with N-methyl-glycine, which is a glycine with a methyl group attached to the nitrogen, and ends with N-methyl-L-valine, another modified valine. The entire peptide is capped with a benzyl ester group, which is a protecting group commonly used in peptide synthesis to prevent unwanted side reactions. N-(3-benzyloxy-4-methyl-2-nitro-benzoyl)-Ls-threonyl->D-valyl->L-prolyl->N-methyl-glycyl->N-methyl-L-valine benzyl ester is likely used in pharmaceutical or chemical research, possibly as a precursor in the synthesis of more complex molecules or as a probe to study specific biological interactions.
The CAS Registry Mumber 6686-01-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,8 and 6 respectively; the second part has 2 digits, 0 and 1 respectively. Calculate Digit Verification of CAS Registry Number 6686-01: (6*6)+(5*6)+(4*8)+(3*6)+(2*0)+(1*1)=117 117 % 10 = 7 So 6686-01-7 is a valid CAS Registry Number.
