Tris(2-propynyl)oxymethane, also known as 1,1,1-tris(2-propynyloxy)methane or TPO, is a colorless, highly flammable liquid with a molecular formula of C?H??O?. It is an organic compound that is widely used as a crosslinking agent in the production of polyurethane foams, particularly for flexible foams used in furniture and bedding. TPO is known for its ability to improve the mechanical properties and durability of the foam, as well as its low toxicity and environmental friendliness compared to other crosslinking agents. It is also used in the synthesis of various organic compounds and as a stabilizer in some polymers. Due to its reactivity, TPO must be handled with care, and appropriate safety measures should be taken during its use and storage.

Check Digit Verification of cas no

The CAS Registry Mumber 83561-30-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,5,6 and 1 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 83561-30:
(7*8)+(6*3)+(5*5)+(4*6)+(3*1)+(2*3)+(1*0)=132
132 % 10 = 2
So 83561-30-2 is a valid CAS Registry Number.
