152521-14-7 Usage
Preparation
4-Aminobenzenesulfonic acid,2-Amino-4-nitrophenol diazo, Coupled with resorcinol, and then translate into 1:1 iron complex.Properties and Applications
yellow light brown. Mainly used for leather shading.Check Digit Verification of cas no
The CAS Registry Mumber 152521-14-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,5,2 and 1 respectively; the second part has 2 digits, 1 and 4 respectively.Calculate Digit Verification of CAS Registry Number 152521-14:
(8*1)+(7*5)+(6*2)+(5*5)+(4*2)+(3*1)+(2*1)+(1*4)=97
97 % 10 = 7
So 152521-14-7 is a valid CAS Registry Number.
