Definition

ChEBI: A macromolecule composed of repeating oxybutylene units.

Preparation

Low molecular weight polymers of tetrahydrofuran were introduced commercially in 1955. The polymers were intended for use in the preparation of flexible polyurethane foams, being terminated by hydroxyl groups: Although these polyethers produced good foams they were rather expensive and were soon displaced by the cheaper propylene oxide-based polyethers. However, these polymers of tetrahydrofuran (commonly called poly(oxytetramethylene)glycol) now find use in the preparation of polyamide, polyester and polyurethane thermoplastic elastomers.Details of the manufacture of polytetrahydrofuran have not been disclosed. Polymerization of tetrahydrofuran can be effected only by cationic initiators. Combinations of metal halides with water are not effective but protic acids (e.g. HCl04) and oxonium salts (e.g. (C2H5)3O+BF4-) are efficient initiators. Polymerization occurs by a ring-opening mechanism involving a tertiary oxonium ion, e.g.

Check Digit Verification of cas no

The CAS Registry Mumber 25190-06-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,1,9 and 0 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 25190-06:
(7*2)+(6*5)+(5*1)+(4*9)+(3*0)+(2*0)+(1*6)=91
91 % 10 = 1
So 25190-06-1 is a valid CAS Registry Number.
