68891-50-9 Usage
General Description
Acrylonitrile/butadiene copolymer is a synthetic rubber made from the polymerization of acrylonitrile and butadiene. It is commonly known by the trade name Nitrile rubber or NBR. The copolymer has a high resistance to oil, fuel, and other chemicals, as well as good physical properties such as high tensile strength and abrasion resistance. Nitrile rubber is also well-known for its excellent resistance to degradation by ozone, sunlight, and weathering. It is commonly used in the automotive and aerospace industries for seals, gaskets, and hoses, as well as in the manufacturing of oil and gas equipment, gloves, and other products that require resistance to oils and chemicals.
Check Digit Verification of cas no
The CAS Registry Mumber 68891-50-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,8,9 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 68891-50:
(7*6)+(6*8)+(5*8)+(4*9)+(3*1)+(2*5)+(1*0)=179
179 % 10 = 9
So 68891-50-9 is a valid CAS Registry Number.
