α,α-Divinylphenylacetonitril, also known as 2,2'-(1,2-Ethenediyl)bisbenzonitrile, is an organic compound with the chemical formula C15H11N. It is a colorless to pale yellow crystalline solid that is soluble in organic solvents. α,α-Divinylphenylacetonitril is primarily used as a monomer in the production of high-performance polymers, such as polyphenylene sulfide (PPS) and polyphenylene ether (PPE), which are known for their excellent thermal stability, chemical resistance, and mechanical properties. These polymers find applications in various industries, including automotive, electronics, and aerospace, where materials with high-temperature resistance and durability are required.
The CAS Registry Mumber 70179-03-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,1,7 and 9 respectively; the second part has 2 digits, 0 and 3 respectively. Calculate Digit Verification of CAS Registry Number 70179-03: (7*7)+(6*0)+(5*1)+(4*7)+(3*9)+(2*0)+(1*3)=112 112 % 10 = 2 So 70179-03-2 is a valid CAS Registry Number.
