18643-56-6 Usage
General Description
p-Benzenedimalononitrile, also known as p-Phenylenebismalononitrile, is a chemical compound that is a derivative of the benzene ring with two malononitrile groups attached to it. It is a white powder with a high melting point and is insoluble in water. p-Benzenedimalononitrile is commonly used in the production of high-performance polymers and resins, as well as in the synthesis of other organic compounds. It is also used as a flame retardant and as a precursor for the preparation of various organic materials. p-Benzenedimalononitrile is considered hazardous and proper safety precautions should be taken when handling it, as it can be harmful if ingested or inhaled and can cause irritation upon contact with skin or eyes.
Check Digit Verification of cas no
The CAS Registry Mumber 18643-56-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,6,4 and 3 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 18643-56:
(7*1)+(6*8)+(5*6)+(4*4)+(3*3)+(2*5)+(1*6)=126
126 % 10 = 6
So 18643-56-6 is a valid CAS Registry Number.
