The chemical in question is a complex polymer formed from the reaction of 1,4-butanediol, 1,3-diisocyanatomethylbenzene, and poly(tetramethylene ether) glycol. This polymer is a type of polyurethane, which is known for its versatility and is used in a wide range of applications due to its properties such as flexibility, durability, and resistance to degradation. The 1,4-butanediol and poly(tetramethylene ether) glycol provide the polymer with hydroxyl groups, which react with the isocyanate groups from 1,3-diisocyanatomethylbenzene to form urethane links. The resulting polymer has a unique structure that combines the properties of the individual components, offering a material with enhanced performance characteristics suitable for various industrial and consumer products.

Check Digit Verification of cas no

The CAS Registry Mumber 9043-71-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,4 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 9043-71:
(6*9)+(5*0)+(4*4)+(3*3)+(2*7)+(1*1)=94
94 % 10 = 4
So 9043-71-4 is a valid CAS Registry Number.
