"4-[(5-chloro-o-tolyl)azo]-3-hydroxy-2-naphtho-o-toluidide" is a complex organic compound with the molecular formula C21H16ClN3O2. It is characterized by a 2-naphtho-o-toluidide structure, which features a naphthalene ring with a hydroxyl group at the 3-position and an o-toluidide group at the 2-position. The o-toluidide group itself is an aniline derivative with a methyl group at the ortho position relative to the amino group. The compound is further distinguished by an azo group (-N=N-) connecting the naphthalene ring to a 5-chloro-o-tolyl group, which is a chlorinated derivative of o-toluene. This chemical is often used as a dye or pigment due to its color properties, and it may also have applications in analytical chemistry for the detection of certain metal ions.

2786-85-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2786-85-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,8 and 6 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2786-85:
(6*2)+(5*7)+(4*8)+(3*6)+(2*8)+(1*5)=118
118 % 10 = 8
So 2786-85-8 is a valid CAS Registry Number.
