3,6,8-Trioxabicyclo[3.2.2]nonane-2,4-dione, also known as triethylene glycol diformate, is a cyclic ester compound with the molecular formula C6H8O5. It is formed by the reaction of triethylene glycol with formic acid, resulting in a nine-membered ring structure containing three ether groups and two ester groups. This chemical is primarily used as a crosslinking agent in the production of polyurethane foams and as a curing agent for epoxy resins. Due to its reactive nature, it is essential to handle it with care, as it can cause irritation to the skin, eyes, and respiratory system.

5686-75-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5686-75-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,8 and 6 respectively; the second part has 2 digits, 7 and 5 respectively.Calculate Digit Verification of CAS Registry Number 5686-75:
(6*5)+(5*6)+(4*8)+(3*6)+(2*7)+(1*5)=129
129 % 10 = 9
So 5686-75-9 is a valid CAS Registry Number.
