Poly(1,4-butanediol), toluylene 2,4-diisocyanate terminated, is a type of polyurethane polymer that is formed by the reaction of 1,4-butanediol with toluylene 2,4-diisocyanate. This chemical compound is characterized by its high molecular weight and is often used in the production of polyurethane elastomers, which are known for their excellent mechanical properties, flexibility, and durability. The terminated isocyanate groups in the polymer chain provide reactive sites for further cross-linking, which can enhance the material's performance in various applications such as coatings, adhesives, and foams. The specific properties and applications of this polymer can vary depending on the degree of polymerization and the ratio of the reactants used in its synthesis.

Check Digit Verification of cas no

The CAS Registry Mumber 9069-50-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,6 and 9 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 9069-50:
(6*9)+(5*0)+(4*6)+(3*9)+(2*5)+(1*0)=115
115 % 10 = 5
So 9069-50-5 is a valid CAS Registry Number.
