Hexadecanethioic acid, S-nonyl ester, also known as palmithioic acid, nonyl ester, or C16H33-SH, is an organic compound with the chemical formula C25H51OS. It is a colorless to pale yellow liquid with a mild, characteristic odor. This ester is formed by the reaction of hexadecanethioic acid (a sulfur analog of a fatty acid) with nonanol (a nine-carbon alcohol). It is primarily used as a synthetic lubricant, particularly in the formulation of metalworking fluids, due to its excellent lubricating properties and thermal stability. Additionally, it has applications in the production of surfactants, emulsifiers, and other specialty chemicals.

Check Digit Verification of cas no

The CAS Registry Mumber 2307-28-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,0 and 7 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2307-28:
(6*2)+(5*3)+(4*0)+(3*7)+(2*2)+(1*8)=60
60 % 10 = 0
So 2307-28-0 is a valid CAS Registry Number.
