5-Chlor-2-nitro-benzotrichlorid and 3-Chlor-6-nitro-benzotrichlorid are two distinct chemical compounds belonging to the class of benzotrichlorides. These compounds are characterized by the presence of a benzene ring with a trichloromethyl group (CCl3) attached to one of the carbon atoms. In 5-Chlor-2-nitro-benzotrichlorid, the chlorine atom is located at the 5th position, while the nitro group (-NO2) is at the 2nd position on the benzene ring. Conversely, in 3-Chlor-6-nitro-benzotrichlorid, the chlorine atom is at the 3rd position, and the nitro group is at the 6th position. Both compounds exhibit different chemical properties and reactivity due to the variation in the positions of the substituents on the benzene ring. These compounds have potential applications in the synthesis of various organic compounds and pharmaceuticals, as well as in the study of chemical reactions involving benzene derivatives.
The CAS Registry Mumber 712-16-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,1 and 2 respectively; the second part has 2 digits, 1 and 6 respectively. Calculate Digit Verification of CAS Registry Number 712-16: (5*7)+(4*1)+(3*2)+(2*1)+(1*6)=53 53 % 10 = 3 So 712-16-3 is a valid CAS Registry Number.
