Dibenzoyl-p-toluoyl-methan, also known as DBM, is a chemical compound with the molecular formula C21H15O3. It is a white crystalline solid that is widely used as a crosslinking agent in the production of polyurethane foams, particularly in the flexible foam industry. DBM functions by reacting with isocyanate groups to form urethane and allophanate linkages, which enhance the strength and durability of the foam. The compound is also known for its low volatility and low toxicity, making it a preferred choice in various applications. It is important to note that DBM is a specific chemical and not a class of chemicals, and it is used for its unique properties in the manufacturing process.

Check Digit Verification of cas no

The CAS Registry Mumber 857-29-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,5 and 7 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 857-29:
(5*8)+(4*5)+(3*7)+(2*2)+(1*9)=94
94 % 10 = 4
So 857-29-4 is a valid CAS Registry Number.
