Aniline, p-(o-tolylazo)-, also known as 4-(2-methylphenylazo)aniline or 4-(o-tolylazo)aniline, is an organic compound with the chemical formula C13H13N3. It is a derivative of aniline, where one of the hydrogen atoms on the aniline molecule is replaced by an azo group (-N=N-) attached to an ortho-tolyl group (2-methylphenyl). This yellow crystalline solid is used as a chemical intermediate in the synthesis of dyes, pigments, and other organic compounds. It is also employed as a reagent in analytical chemistry for the detection and determination of certain metal ions, such as copper and nickel, due to its ability to form colored complexes with these ions. The compound is sensitive to light and heat, and it is typically stored in a cool, dark place to prevent decomposition.

6690-52-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6690-52-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,9 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6690-52:
(6*6)+(5*6)+(4*9)+(3*0)+(2*5)+(1*2)=114
114 % 10 = 4
So 6690-52-4 is a valid CAS Registry Number.
