"(Methoxymethyl)trimethyltin" is an organotin compound with the chemical formula (CH3OCH2)Sn(CH3)3. It is a colorless liquid that is soluble in organic solvents. (methoxymethyl)trimethyltin is primarily used as a catalyst in the production of polyurethane foams and as a stabilizer for various polymers. It is also known for its biocidal properties and has been used in antifouling paints. However, due to concerns over its environmental impact and toxicity, especially to marine life, its use has been restricted or banned in many countries. The compound is characterized by its reactivity, where the methoxymethyl group can undergo substitution reactions, and it is sensitive to hydrolysis, which can lead to the formation of toxic tin(IV) species.

Check Digit Verification of cas no

The CAS Registry Mumber 4649-80-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,4 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4649-80:
(6*4)+(5*6)+(4*4)+(3*9)+(2*8)+(1*0)=113
113 % 10 = 3
So 4649-80-3 is a valid CAS Registry Number.
