General Description
2,4-Dichloro-5-fluoronitrobenzene is a chemical compound with the molecular formula C6H3Cl2NO2F. It is a pale yellow solid that is sparingly soluble in water. 2,4-Dichloro-5-fluoronitrobenzene is primarily used as an intermediate in the synthesis of pharmaceuticals and agrochemicals. It is also used as a building block in organic synthesis, particularly in the production of dyes and other specialty chemicals. 2,4-Dichloro-5-fluoronitrobenzene is known for its strong, unpleasant odor and should be handled with caution due to its toxic and irritant properties.
Check Digit Verification of cas no
The CAS Registry Mumber 2105-59-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,0 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2105-59:
(6*2)+(5*1)+(4*0)+(3*5)+(2*5)+(1*9)=51
51 % 10 = 1
So 2105-59-1 is a valid CAS Registry Number.
