18684-11-2 Usage
General Description
Trimethyl(octadecyl)ammonium methyl sulphate is a quaternary ammonium compound that is commonly used as a cationic surfactant in various industrial and household products. It is composed of a long hydrophobic alkyl chain, consisting of 18 carbon atoms, attached to a positively charged quaternary nitrogen atom. This structure allows the chemical to lower the surface tension of liquids and increase their ability to mix with non-polar substances, making it an effective ingredient in fabric softeners, hair conditioners, and detergents. Additionally, it has antimicrobial properties which makes it suitable for use in disinfectants and sanitizers. However,
Check Digit Verification of cas no
The CAS Registry Mumber 18684-11-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,6,8 and 4 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 18684-11:
(7*1)+(6*8)+(5*6)+(4*8)+(3*4)+(2*1)+(1*1)=132
132 % 10 = 2
So 18684-11-2 is a valid CAS Registry Number.
