39473-89-7 Usage
General Description
Ferrihydrite is a mineral compound that consists of iron, oxygen, and water. It is a naturally occurring material that is commonly found in soils, sediments, and aquatic environments. Ferrihydrite has a high surface area and is known for its strong reactivity and ability to adsorb a wide range of contaminants, including heavy metals and organic pollutants. It has been studied for its potential use in environmental remediation, as well as in various industrial applications such as wastewater treatment and catalysis. In addition, ferrihydrite has been of interest to geologists and scientists studying the formation and transformation of minerals in natural systems.
Check Digit Verification of cas no
The CAS Registry Mumber 39473-89-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,4,7 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 39473-89:
(7*3)+(6*9)+(5*4)+(4*7)+(3*3)+(2*8)+(1*9)=157
157 % 10 = 7
So 39473-89-7 is a valid CAS Registry Number.
