54210-32-1 Usage
General Description
1H-Pyrazole,1-methyl-3-nitro-(9CI) is a chemical compound with the molecular formula C4H5N3O2. It is a nitro derivative of 1-methylpyrazole, which is commonly used as a building block in the synthesis of pharmaceuticals and other organic compounds. The nitro group on the pyrazole ring makes this compound potentially useful as a precursor for the synthesis of other nitrogen-containing compounds such as heterocyclic compounds and pharmaceutical substances. Its structure and properties make 1H-Pyrazole,1-methyl-3-nitro-(9CI) important in the field of organic synthesis and medicinal chemistry. However, as a nitro compound, it may also have explosive properties and it is important to handle it with care and in a controlled manner.
Check Digit Verification of cas no
The CAS Registry Mumber 54210-32-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,2,1 and 0 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 54210-32:
(7*5)+(6*4)+(5*2)+(4*1)+(3*0)+(2*3)+(1*2)=81
81 % 10 = 1
So 54210-32-1 is a valid CAS Registry Number.
