8-Isocyanato-chromen-2-one is a chemical compound with the molecular formula C9H5NO2. It is a derivative of chromone, a heterocyclic organic compound consisting of a benzene ring fused to a pyran ring. The presence of an isocyanate group (-NCO) at the 8-position and a carbonyl group (C=O) at the 2-position gives 8-isocyanato-chromen-2-one unique properties and reactivity. It is primarily used as an intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other organic compounds due to its ability to form urea and carbamate derivatives upon reaction with amines and alcohols, respectively. The compound is typically synthesized through the reaction of 8-aminochromen-2-one with phosgene or a similar isocyanate source. It is important to handle 8-isocyanato-chromen-2-one with care, as isocyanates are known to be toxic and can cause severe health issues upon exposure.

2631-74-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2631-74-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,3 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.Calculate Digit Verification of CAS Registry Number 2631-74:
(6*2)+(5*6)+(4*3)+(3*1)+(2*7)+(1*4)=75
75 % 10 = 5
So 2631-74-5 is a valid CAS Registry Number.
