DL-erythro-3-methyl-4-phenyl-hexan-3,4-diol-2,5-dione, also known as DL-DOPA, is a chemical compound with the molecular formula C13H16O4. It is a synthetic derivative of the amino acid L-DOPA, which is a precursor to the neurotransmitters dopamine, norepinephrine, and epinephrine. DL-DOPA is used in the treatment of Parkinson's disease, as it can cross the blood-brain barrier and be converted into dopamine, thereby helping to alleviate symptoms associated with the condition. The compound is a white crystalline solid and is soluble in water, ethanol, and methanol. It is synthesized through a series of chemical reactions, including the condensation of pyruvic acid with phenylalanine, followed by reduction and oxidation steps. DL-DOPA is a racemic mixture, meaning it contains equal parts of the D and L isomers, which is why it is referred to as DL-DOPA.
The CAS Registry Mumber 5848-85-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,4 and 8 respectively; the second part has 2 digits, 8 and 5 respectively. Calculate Digit Verification of CAS Registry Number 5848-85: (6*5)+(5*8)+(4*4)+(3*8)+(2*8)+(1*5)=131 131 % 10 = 1 So 5848-85-1 is a valid CAS Registry Number.
