L-Phenylalanine, 3,4-dihydroxy-2-methyl-, also known as L-DOPA or Levodopa, is a naturally occurring amino acid and a precursor to the neurotransmitters dopamine, norepinephrine, and epinephrine. It is a white crystalline powder with a molecular formula of C9H11NO4 and a molecular weight of 197.19 g/mol. L-DOPA is primarily used in the treatment of Parkinson's disease, as it can cross the blood-brain barrier and be converted into dopamine, which is deficient in the brains of Parkinson's patients. Additionally, it has been studied for its potential use in treating other neurological disorders and as a precursor in the synthesis of various pharmaceuticals.
The CAS Registry Mumber 779-08-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,7 and 9 respectively; the second part has 2 digits, 0 and 8 respectively. Calculate Digit Verification of CAS Registry Number 779-08: (5*7)+(4*7)+(3*9)+(2*0)+(1*8)=98 98 % 10 = 8 So 779-08-8 is a valid CAS Registry Number.
