1,2,3,4-tetrachloro-5-pentachloroethyl-benzene is a complex organic compound with the molecular formula C8HCl9. It is a derivative of benzene, where four chlorine atoms are attached to the 1, 2, 3, and 4 positions, and a pentachloroethyl group is attached to the 5 position. 1,2,3,4-tetrachloro-5-pentachloroethyl-benzene is highly chlorinated, with a total of nine chlorine atoms. Due to its high chlorine content, it is likely to be a persistent and potentially hazardous substance, with potential applications in chemical research or as an intermediate in the synthesis of other chlorinated compounds. However, it is important to note that the environmental and health impacts of such compounds should be carefully considered, as they may pose risks due to their stability and potential for bioaccumulation.
The CAS Registry Mumber 2136-94-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,3 and 6 respectively; the second part has 2 digits, 9 and 4 respectively. Calculate Digit Verification of CAS Registry Number 2136-94: (6*2)+(5*1)+(4*3)+(3*6)+(2*9)+(1*4)=69 69 % 10 = 9 So 2136-94-9 is a valid CAS Registry Number.
