Poly(oxy-1,4-butanedioly), α-hydro-ω-hydroxy-, polymer with 1,1-methylenebis4-isocyanatobenzene is a complex chemical compound that is essentially a polyether polyol, which is a type of polymer. This specific polyether polyol is characterized by its hydroxyl end groups (α-hydro-ω-hydroxy), indicating that it has a hydroxyl group at both the beginning (alpha) and the end (omega) of the polymer chain. The polymer is formed by the reaction with 1,1-methylenebis4-isocyanatobenzene, which is a diisocyanate compound commonly known as methylene diphenyl diisocyanate (MDI). This reaction results in the formation of a urethane linkage, which is a key component in the production of polyurethane materials. The resulting polymer is used in various applications, including the production of polyurethane foams, coatings, and elastomers, due to its unique properties such as flexibility, durability, and resistance to wear.

Check Digit Verification of cas no

The CAS Registry Mumber 9048-58-2 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 8 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 9048-58:
(6*9)+(5*0)+(4*4)+(3*8)+(2*5)+(1*8)=112
112 % 10 = 2
So 9048-58-2 is a valid CAS Registry Number.
