2-Naphthalenol, 1-[(2-hydroxyphenyl)azo]-, also known as 1-(2-hydroxyphenylazo)-2-naphthol, is an organic compound with the chemical formula C16H12N2O2. It is a derivative of naphthalene, featuring an azo group (-N=N-) connecting a 2-naphthol moiety to a 2-hydroxyphenyl group. This yellow crystalline solid is soluble in organic solvents and has applications in the synthesis of dyes and pigments, particularly in the production of azo dyes. It is important to note that 2-Naphthalenol, 1-[(2-hydroxyphenyl)azo]-, like many azo compounds, may have potential health and environmental concerns, and appropriate safety measures should be taken during its handling and use.

4866-98-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4866-98-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,6 and 6 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4866-98:
(6*4)+(5*8)+(4*6)+(3*6)+(2*9)+(1*8)=132
132 % 10 = 2
So 4866-98-2 is a valid CAS Registry Number.
