4,4'-methylenebis[N,N-dimethyl-2-nitroaniline], also known as DMNA or MOCA, is an organic compound with the chemical formula C10H16N4O4. It is a yellow crystalline solid that is used as a curing agent for epoxy resins, particularly in the production of high-performance composite materials. DMNA is known for its high reactivity and ability to improve the mechanical properties of the cured epoxy resin. However, it is also classified as a carcinogenic substance, and its use is restricted in many countries due to health and environmental concerns. The compound is synthesized by reacting formaldehyde with N,N-dimethyl-2-nitroaniline, and it is characterized by its two nitro groups and a methylene bridge connecting the two aniline units.

89-09-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 89-09-8 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 89-09:
(4*8)+(3*9)+(2*0)+(1*9)=68
68 % 10 = 8
So 89-09-8 is a valid CAS Registry Number.
