26148-42-5 Usage
General Description
2-(pyridin-2-ylamino)phenol, also known as 2-pyridylazo-2-naphthol (PAN), is a chemical compound that is used as a spectrophotometric reagent for the determination of various metals, particularly those of the transition metal group such as cadmium, copper, and zinc. It forms colored complexes with these metals, allowing for their quantitative analysis using spectrophotometry. Additionally, PAN is also used in organic synthesis as a building block in the production of dyes and pigments, and as a pH indicator in analytical chemistry. However, it is important to handle this chemical with caution, as it is toxic and can cause skin and eye irritation upon contact.
Check Digit Verification of cas no
The CAS Registry Mumber 26148-42-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,1,4 and 8 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 26148-42:
(7*2)+(6*6)+(5*1)+(4*4)+(3*8)+(2*4)+(1*2)=105
105 % 10 = 5
So 26148-42-5 is a valid CAS Registry Number.
