Trimethyl-acetyl isocyanate, also known as trimethylacetyl isocyanate or TMAI, is an organic compound with the chemical formula C6H9NO. It is a colorless liquid that is highly reactive and toxic, and it is used as a chemical intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals. TMAI is produced by the reaction of trimethylacetic acid with phosgene, and it is known for its ability to form stable carbamates with alcohols and amines. Due to its high reactivity and potential health risks, it is essential to handle TMAI with extreme caution and in accordance with proper safety protocols.

4461-20-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4461-20-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,6 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.Calculate Digit Verification of CAS Registry Number 4461-20:
(6*4)+(5*4)+(4*6)+(3*1)+(2*2)+(1*0)=75
75 % 10 = 5
So 4461-20-5 is a valid CAS Registry Number.
