1-Oxaspiro[2.5]octane, 2-isocyanato- is a chemical compound with the molecular formula C8H13NO2. It is a heterocyclic compound, specifically a spiro compound, which consists of a seven-membered ring (a heptane) fused to a five-membered ring (a cyclopentane) with an oxygen atom in the spiro position. The isocyanate functional group (-NCO) is attached to the second carbon atom of the spiro compound. This chemical is primarily used as a monomer in the synthesis of polyurethane polymers, which are widely used in various industries, including coatings, adhesives, and foams. Due to its reactive isocyanate group, it is essential to handle 1-Oxaspiro[2.5]octane, 2-isocyanato- with caution, as it can cause irritation and potential health hazards if not properly managed.
The CAS Registry Mumber 89849-18-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,8,4 and 9 respectively; the second part has 2 digits, 1 and 8 respectively. Calculate Digit Verification of CAS Registry Number 89849-18: (7*8)+(6*9)+(5*8)+(4*4)+(3*9)+(2*1)+(1*8)=203 203 % 10 = 3 So 89849-18-3 is a valid CAS Registry Number.
