12269-88-4 Usage
Preparation
2-Amino-4-nitrophenol diazo, and 4-(3-Methyl-5-oxo-4,5-dihydropyrazol-1-yl)benzenesulfonic acid coupling, and then turn it into 1:2 iron complex.Properties and Applications
yellow light brown. Mainly used for leather color.Check Digit Verification of cas no
The CAS Registry Mumber 12269-88-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,6 and 9 respectively; the second part has 2 digits, 8 and 8 respectively.Calculate Digit Verification of CAS Registry Number 12269-88:
(7*1)+(6*2)+(5*2)+(4*6)+(3*9)+(2*8)+(1*8)=104
104 % 10 = 4
So 12269-88-4 is a valid CAS Registry Number.
