The chemical compound in question is a peptide-like structure with a sequence of amino acids and a hydroxy acid, terminated with a hydrobromide salt. It starts with N-methyl-D-valine, an amino acid derivative where the nitrogen is methylated and the chirality is D (right-handed). This is followed by L-2-hydroxy-3-methyl-butyryl, which is a hydroxy acid with a 3-methyl-butyryl group (a 4-carbon chain with a hydroxyl group at the 2nd carbon and a methyl group at the 3rd carbon). The sequence continues with N-methyl-L-valine, another amino acid derivative similar to the first but with L (left-handed) chirality. The compound ends with L-2-hydroxy-3-methyl-butyric acid, which is the carboxylic acid form of the hydroxy acid mentioned earlier. The entire structure is a hydrobromide salt, indicating that it has been treated with hydrobromic acid to form a salt, which can affect its solubility and stability. N-methyl-D-valyl->L-2-hydroxy-3-methyl-butyryl->N-methyl-L-valyl->L-2-hydroxy-3-methyl-butyric acid; hydrobromide is likely to be used in pharmaceutical or chemical research due to its unique structure and potential biological activity.
The CAS Registry Mumber 4217-10-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,1 and 7 respectively; the second part has 2 digits, 1 and 0 respectively. Calculate Digit Verification of CAS Registry Number 4217-10: (6*4)+(5*2)+(4*1)+(3*7)+(2*1)+(1*0)=61 61 % 10 = 1 So 4217-10-1 is a valid CAS Registry Number.
