Bis-(4-iodo-phenyl)-carbodiimide, also known as 1,1'-(carbonyldi-4,1-phenylene)bis-1,2-diiodoethane, is a chemical compound with the molecular formula C14H8I4N2O2. It is a white crystalline solid that is widely used in organic synthesis as a coupling agent, particularly in the formation of peptide bonds. This reagent activates carboxylic acids, facilitating their reaction with amines to form amides. It is also employed in the synthesis of various pharmaceuticals, agrochemicals, and other bioactive compounds. Due to its high reactivity and the presence of iodine atoms, bis-(4-iodo-phenyl)-carbodiimide can be hazardous and requires careful handling.
The CAS Registry Mumber 726-43-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,2 and 6 respectively; the second part has 2 digits, 4 and 3 respectively. Calculate Digit Verification of CAS Registry Number 726-43: (5*7)+(4*2)+(3*6)+(2*4)+(1*3)=72 72 % 10 = 2 So 726-43-2 is a valid CAS Registry Number.
