1,4-Naphthalenediyldiisocyanate, also known as NDI, is an organic compound widely used in the production of polyurethane plastics, elastomers, and foams. It is a colorless to pale yellow, crystalline solid with a strong, pungent odor. The chemical formula for 1,4-Naphthalenediyldiisocyanate is C12H6N2O2, and it has a molecular weight of 210.19 g/mol. NDI is synthesized by reacting naphthalene with phosgene in the presence of a catalyst, resulting in a diisocyanate compound with two isocyanate functional groups attached to a naphthalene ring. Due to its high reactivity, it is essential to handle NDI with proper safety precautions, as it can cause skin and respiratory irritation, and prolonged exposure may lead to more severe health issues.

46494-42-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 46494-42-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,6,4,9 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 46494-42:
(7*4)+(6*6)+(5*4)+(4*9)+(3*4)+(2*4)+(1*2)=142
142 % 10 = 2
So 46494-42-2 is a valid CAS Registry Number.
