Preparation
3,3′-Dimethylbenzidine double nitriding, in alkaline conditions first and 4-Amino-5-hydroxynaphthalene-2,7-disulfonic acid?coupling, and then in alkaline conditions and 7-Amino-4-hydroxynaphthalene-2-sulfonic acid coupling.
Check Digit Verification of cas no
The CAS Registry Mumber 6420-22-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,2 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6420-22:
(6*6)+(5*4)+(4*2)+(3*0)+(2*2)+(1*2)=70
70 % 10 = 0
So 6420-22-0 is a valid CAS Registry Number.
