83-81-8 Usage
General Description
O-Phthalic acid bis(diethylamide) is a chemical compound that is used as a plasticizer, a substance added to plastics to increase their flexibility and durability. It is also utilized as a corrosion inhibitor, to prevent metal surfaces from rusting or corroding. The compound is derived from o-phthalic acid, a common organic compound used primarily in the production of polymers and resins. O-phthalic acid bis(diethylamide) has low volatility and high thermal stability, making it suitable for a wide range of industrial applications. However, it is important to handle this chemical with caution, as it can cause skin and eye irritation, and can be harmful if swallowed or inhaled.
Check Digit Verification of cas no
The CAS Registry Mumber 83-81-8 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 83-81:
(4*8)+(3*3)+(2*8)+(1*1)=58
58 % 10 = 8
So 83-81-8 is a valid CAS Registry Number.
