Perfluoradipinsaeure-diphenylester, also known as perfluorododecanoic acid diphenyl ester, is a synthetic chemical compound characterized by its perfluorinated alkyl chain and diphenyl ester functional group. Perfluoradipinsaeure-diphenylester is derived from perfluorododecanoic acid, where the carboxylic acid group is esterified with two phenol molecules. It is known for its unique properties, such as resistance to heat, water, and oil, which can make it useful in various industrial applications. However, due to its persistence and potential environmental impact, there is a growing concern about its use and disposal, leading to increased scrutiny and regulation in many regions.
The CAS Registry Mumber 2146-08-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,4 and 6 respectively; the second part has 2 digits, 0 and 8 respectively. Calculate Digit Verification of CAS Registry Number 2146-08: (6*2)+(5*1)+(4*4)+(3*6)+(2*0)+(1*8)=59 59 % 10 = 9 So 2146-08-9 is a valid CAS Registry Number.
