1-oxy-5-phenyl-pyrazin-2-ylamine, also known as 5-phenyl-2-oxopyrazin-1-amine, is a chemical compound with the molecular formula C11H9N3O. It is a derivative of pyrazine, a heterocyclic compound consisting of a six-membered aromatic ring with two nitrogen atoms. The presence of a phenyl group (C6H5) at the 5-position and an oxo group (C=O) at the 2-position gives 1-oxy-5-phenyl-pyrazin-2-ylamine its unique structure and properties. This organic compound may have potential applications in pharmaceuticals, agrochemicals, or as an intermediate in the synthesis of other complex molecules. However, further research and characterization are needed to fully understand its properties and potential uses.

Check Digit Verification of cas no

The CAS Registry Mumber 25844-70-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,8,4 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 25844-70:
(7*2)+(6*5)+(5*8)+(4*4)+(3*4)+(2*7)+(1*0)=126
126 % 10 = 6
So 25844-70-6 is a valid CAS Registry Number.
