Dimethyl N',N'-hydrazine diacetate, also known as Unsymmetrical dimethyl hydrazine (UDMH), is an organic compound with the chemical formula C4H10N2O4. It is a colorless, oily liquid that is soluble in water and serves as a rocket propellant and fuel. UDMH is a derivative of hydrazine, with two methyl groups attached to the nitrogen atoms, and two acetate groups attached to the remaining nitrogen atoms. It is known for its high energy density and low freezing point, making it suitable for use in cryogenic rocket fuels. However, it is also toxic and can cause severe health issues if ingested or inhaled, necessitating proper handling and storage.
The CAS Registry Mumber 2387-25-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,8 and 7 respectively; the second part has 2 digits, 2 and 5 respectively. Calculate Digit Verification of CAS Registry Number 2387-25: (6*2)+(5*3)+(4*8)+(3*7)+(2*2)+(1*5)=89 89 % 10 = 9 So 2387-25-9 is a valid CAS Registry Number.
