Biochem/physiol Actions
L-Histidine is involved in the one-carbon unit metabolism. It is associated with protein methylation. L-Histidine is a part of hemoglobin structure and function. L-Histidine is a component of dipeptides with antioxidative property. Histidine serves as a precursor for the formation of histamine, which is associated with allergic responses. Urocanic acid, an immune response modulator in skin is also biosynthesised from histidine.
Check Digit Verification of cas no
The CAS Registry Mumber 4998-57-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,9 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4998-57:
(6*4)+(5*9)+(4*9)+(3*8)+(2*5)+(1*7)=146
146 % 10 = 6
So 4998-57-6 is a valid CAS Registry Number.
