Tris(3-chloropropyl) orthoformate, also known as TPO, is a colorless liquid chemical compound with the formula (C3H6Cl)3C3H3O3. It is widely used as a crosslinking agent in the production of polyurethane foams, particularly for flexible foams. TPO is known for its ability to react with isocyanates, which are commonly used in the formation of polyurethane polymers. It is also recognized for its relatively low toxicity compared to other crosslinking agents, making it a safer alternative in certain applications. The compound is produced by the reaction of orthoformic acid with 3-chloropropyl chloride. Due to its reactivity and potential health and environmental concerns, TPO is typically handled with care in controlled industrial settings.

Check Digit Verification of cas no

The CAS Registry Mumber 38565-66-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,5,6 and 5 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 38565-66:
(7*3)+(6*8)+(5*5)+(4*6)+(3*5)+(2*6)+(1*6)=151
151 % 10 = 1
So 38565-66-1 is a valid CAS Registry Number.
