12217-75-3 Usage
Preparation
3-Aminobenzenesulfonic acid diazo, and (2-Methoxyphenylamino)methanesulfonic acid coupling, then the water with sulfonic acid base, compounds (A);7-Aminonaphthalene-1,3-disulfonic acid diazo, and a coupling m-Toluidine, compound (B). Then will molecules of the A and B mixture to light gasification.Properties and Applications
yellow. Used for paper color.Check Digit Verification of cas no
The CAS Registry Mumber 12217-75-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,1 and 7 respectively; the second part has 2 digits, 7 and 5 respectively.Calculate Digit Verification of CAS Registry Number 12217-75:
(7*1)+(6*2)+(5*2)+(4*1)+(3*7)+(2*7)+(1*5)=73
73 % 10 = 3
So 12217-75-3 is a valid CAS Registry Number.
