Bakelite is a pioneering synthetic plastic material, invented in 1907 by Belgian chemist Dr. Leo Baekeland. It is the first fully synthetic plastic, made from a combination of phenol and formaldehyde through a condensation reaction, resulting in a thermosetting polymer. Bakelite is known for its heat resistance, electrical non-conductivity, and chemical stability, making it suitable for a wide range of applications, including electrical insulators, household items, and jewelry. Its durability and resistance to warping have contributed to its historical significance in the development of the plastics industry.

Check Digit Verification of cas no

The CAS Registry Mumber 9012-45-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,1 and 2 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 9012-45:
(6*9)+(5*0)+(4*1)+(3*2)+(2*4)+(1*5)=77
77 % 10 = 7
So 9012-45-7 is a valid CAS Registry Number.
