67989-30-4 Usage
General Description
Fatty acids, C18-unsaturated, dimers, polymers with ethylenediamine, hexamethylenediamine, and propionic acid are complex chemical compounds formed by the polymerization of unsaturated C18 fatty acids, ethylenediamine, hexamethylenediamine, and propionic acid. This chemical mixture is primarily used in industrial applications, specifically in the production of adhesives and sealants. These substances are largely oil-resistant, color-stable, and exhibit excellent hydrolytic stability. Though their physical and chemical properties vary depending on the composition, typically, they appear as slightly yellow to amber viscous liquids. Safety measures should be taken while handling these chemicals as they can be harmful or fatal if swallowed, inhaled or come into contact with the skin.
Check Digit Verification of cas no
The CAS Registry Mumber 67989-30-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,9,8 and 9 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 67989-30:
(7*6)+(6*7)+(5*9)+(4*8)+(3*9)+(2*3)+(1*0)=194
194 % 10 = 4
So 67989-30-4 is a valid CAS Registry Number.
