General Description
2-(2-Pyridylazo)-1-naphthol, also known as PAN, is an organic compound commonly used as a spectrophotometric reagent for the determination of various metal ions, such as aluminum, beryllium, and chromium. It is a red, crystalline powder that is soluble in organic solvents but insoluble in water. PAN is also used as a pH indicator, with a color change from red to yellow as the pH increases. It is important to handle PAN with care, as it may be toxic if ingested or inhaled, and it can cause skin and eye irritation. Due to its potential health hazards, proper safety measures must be taken when handling and using this chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 10335-31-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,3,3 and 5 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 10335-31:
(7*1)+(6*0)+(5*3)+(4*3)+(3*5)+(2*3)+(1*1)=56
56 % 10 = 6
So 10335-31-6 is a valid CAS Registry Number.
