The chemical in question is a cyclic peptide, which is a type of compound formed by the linkage of amino acids in a cyclic structure. This specific cyclic peptide is composed of a repeating sequence of four different amino acid residues: D-2-hydroxy-3-methyl-butyryl, D-valyl, L-2-hydroxy-propionyl, and D-valyl. The sequence starts with D-2-hydroxy-3-methyl-butyryl, followed by D-valyl, then L-2-hydroxy-propionyl, and ends with another D-valyl. This pattern repeats, creating a cyclic structure. The presence of both D- and L-isomers in the sequence indicates that it is a mixture of enantiomers, which is common in natural peptides. The cyclic nature of the peptide suggests that it may have unique properties compared to linear peptides, such as increased stability and specific biological activities.
The CAS Registry Mumber 3990-33-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,9 and 0 respectively; the second part has 2 digits, 3 and 3 respectively. Calculate Digit Verification of CAS Registry Number 3990-33: (6*3)+(5*9)+(4*9)+(3*0)+(2*3)+(1*3)=108 108 % 10 = 8 So 3990-33-8 is a valid CAS Registry Number.
