N,N'-Methylene-bis(2-hydroxy-4-phenyl-but-3-ensaeure-amid), also known as 4,4'-methylenedianiline (MDA), is an organic compound with the chemical formula C15H16N2O2. It is a white crystalline solid that is widely used in the production of polyurethane foams and elastomers due to its ability to act as a chain extender. MDA is formed by the condensation of two molecules of 2-hydroxy-4-phenyl-but-3-ensaeure-amid (also known as 2-hydroxy-4-phenylbutyramide) with a methylene bridge connecting the two amide groups. N.N'-Methylen-bis-<2-hydroxy-4-phenyl-but-3-ensaeure-amid> is known for its high reactivity and is used in various industrial applications, particularly in the manufacturing of flexible and rigid foams. However, it is also recognized for its potential health and environmental risks, and as such, its use is subject to strict regulations.

805-78-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 805-78-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,0 and 5 respectively; the second part has 2 digits, 7 and 8 respectively.Calculate Digit Verification of CAS Registry Number 805-78:
(5*8)+(4*0)+(3*5)+(2*7)+(1*8)=77
77 % 10 = 7
So 805-78-7 is a valid CAS Registry Number.
