4342-33-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4342-33-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,4 and 2 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4342-33:
(6*4)+(5*3)+(4*4)+(3*2)+(2*3)+(1*3)=70
70 % 10 = 0
So 4342-33-0 is a valid CAS Registry Number.

Urethane prepolymer
-
, (2008/06/13)
A polyurethane prepolymer composition comprising (1) not less than 0.65 by weight of the idealized adduct from trimethylolpropane with 3 moles of 3-isocyanatomethyl-3,5,5-trimethylcyclohexylisocyanate and (2) not more than 0.05 by weight of 3-isocyanatomethyl-3,5,5-trimethylcyclohexylisocyanate relative to the whole composition is very suitable for an isocyanate component of a two-package urethane coating and gives a coating film having excellent gloss, weathering resistance, adhesivity and impact resistance.
