Dioctyl ethylphosphonate, also known as DOEP, is a colorless liquid chemical compound with the molecular formula C16H35O3P. It is an organophosphorus compound widely used as a plasticizer, primarily in the production of flexible polyvinyl chloride (PVC) products such as films, hoses, and cables. DOEP is known for its excellent low-temperature flexibility, resistance to extraction, and compatibility with various polymers. It is also used as a flame retardant and a stabilizer in the manufacturing of certain plastics. Due to its potential health and environmental concerns, it is essential to handle and dispose of DOEP responsibly, following proper safety guidelines and regulations.
The CAS Registry Mumber 6156-13-4 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 6 respectively; the second part has 2 digits, 1 and 3 respectively. Calculate Digit Verification of CAS Registry Number 6156-13: (6*6)+(5*1)+(4*5)+(3*6)+(2*1)+(1*3)=84 84 % 10 = 4 So 6156-13-4 is a valid CAS Registry Number.
