2-Pentanone, 1,1-dichloro-, also known as methyl ethyl ketone (MEK), is an organic compound with the chemical formula C5H10Cl2O. It is a colorless liquid with a pungent odor and is widely used as a solvent in various industries, including paint, varnish, and adhesive manufacturing. MEK is also employed as a cleaning agent and degreaser, as well as a chemical intermediate in the production of other chemicals. Due to its volatility and potential health risks, it is essential to handle MEK with proper safety measures, such as using gloves, goggles, and a well-ventilated workspace.

Check Digit Verification of cas no

The CAS Registry Mumber 2648-58-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,4 and 8 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2648-58:
(6*2)+(5*6)+(4*4)+(3*8)+(2*5)+(1*8)=100
100 % 10 = 0
So 2648-58-0 is a valid CAS Registry Number.
