Dihexyl ethylphosphonate, also known as DEHP, is a colorless, odorless, and oily liquid chemical compound with the molecular formula C18H39O4P. It is widely used as a plasticizer, primarily in the production of polyvinyl chloride (PVC) products, to increase flexibility and durability. DEHP is also employed in various industrial applications, such as adhesives, sealants, and lubricants. However, it has raised concerns due to its potential health and environmental risks, as it can leach out of products and accumulate in the environment, posing risks to human health and wildlife. As a result, there has been a growing trend towards the use of alternative, less harmful plasticizers.

Check Digit Verification of cas no

The CAS Registry Mumber 6151-92-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,1,5 and 1 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6151-92:
(6*6)+(5*1)+(4*5)+(3*1)+(2*9)+(1*2)=84
84 % 10 = 4
So 6151-92-4 is a valid CAS Registry Number.
