40372-66-5 Usage
General Description
2-Phosphonobutane-1,2,4-tricarboxylic acid sodium salt, also referred to as PBTC salt, is a chemical compound primarily used as an effective corrosion and scale inhibitor in various industries. This organic phosphorus compound is noted for its exceptional chelating ability, hygroscopic properties and strong oxidation resistance. It is characterized by its low phosphorus content which makes it particularly eco-friendly. It is typically applied in circulating cooling water systems in power plants, iron & steel factories, chemical plants, etc. Its high performance in controlling scale formation and mitigating the impact of high salt concentration makes it a preferred choice in water treatment processes.Check Digit Verification of cas no
The CAS Registry Mumber 40372-66-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,3,7 and 2 respectively; the second part has 2 digits, 6 and 6 respectively.Calculate Digit Verification of CAS Registry Number 40372-66:
(7*4)+(6*0)+(5*3)+(4*7)+(3*2)+(2*6)+(1*6)=95
95 % 10 = 5
So 40372-66-5 is a valid CAS Registry Number.
