Pentaiodo-ethane, also known as C2I5H2, is an organoiodine compound with the molecular formula C2H2I5. It is a colorless, crystalline solid that is highly sensitive to light and heat. Pentaiodo-ethane is a derivative of ethane, where five hydrogen atoms are replaced by iodine atoms. Due to its high iodine content, it has unique chemical properties and is used in various applications, such as a precursor in the synthesis of other organoiodine compounds, a reagent in organic synthesis, and a potential candidate for medical imaging due to its high atomic number. However, it is important to note that pentaiodo-ethane is a hazardous substance and requires proper handling and storage due to its potential toxicity and environmental impact.
The CAS Registry Mumber 594-67-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,9 and 4 respectively; the second part has 2 digits, 6 and 7 respectively. Calculate Digit Verification of CAS Registry Number 594-67: (5*5)+(4*9)+(3*4)+(2*6)+(1*7)=92 92 % 10 = 2 So 594-67-2 is a valid CAS Registry Number.
