Phosphorsaeure-benzoylamid-dinonylester, also known as dinonyl benzoyl phosphate or DNBP, is a chemical compound with the formula C21H37O4P. It is an organophosphorus compound that is widely used as a plasticizer, particularly in the production of flexible polyvinyl chloride (PVC) products. DNBP is known for its excellent low-temperature flexibility, resistance to extraction, and good electrical properties. It is commonly used in applications such as automotive parts, hoses, gaskets, and cable insulation. However, due to concerns over its potential health and environmental impacts, there has been a shift towards the use of alternative plasticizers in some regions.
The CAS Registry Mumber 3808-05-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,0 and 8 respectively; the second part has 2 digits, 0 and 5 respectively. Calculate Digit Verification of CAS Registry Number 3808-05: (6*3)+(5*8)+(4*0)+(3*8)+(2*0)+(1*5)=87 87 % 10 = 7 So 3808-05-7 is a valid CAS Registry Number.
