327-91-3 Usage
General Description
1-Chloro-5-fluoro-2,4-dinitrobenzene, also known as 5-F-2,4-DNP, is a halogenated nitrobenzene compound that is used in organic synthesis and lab research. As a volatile organic compound, it appears as a solid crystalline structure. It contains chlorine and fluorine atoms, which contribute to its reactivity and stability. Moreover, due to the presence of nitro groups, it exhibits properties of a strong nitroaromatic compound, making it a useful reagent in the production of various chemical products. However, due to its reactive nature, it should be handled with care, as it has potential risks associated with its use, including potential for flammability, toxicity, and environmental hazards.
Check Digit Verification of cas no
The CAS Registry Mumber 327-91-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,2 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 327-91:
(5*3)+(4*2)+(3*7)+(2*9)+(1*1)=63
63 % 10 = 3
So 327-91-3 is a valid CAS Registry Number.
