Heptafluoro-n-propanselenylchloride, also known as 1-chloro-1,1,2,2,3,3,3-heptafluoropropane or CF3CF2CF2SeCl, is a colorless, volatile liquid with a molecular formula of C3ClF7Se. It is a derivative of n-propaneselenyl chloride, where the hydrogen atoms are replaced by fluorine atoms, resulting in a highly electronegative and reactive compound. This chemical is primarily used as a reagent in organic synthesis, particularly in the preparation of various organoselenium compounds. Due to its high reactivity, it is essential to handle heptafluoro-n-propanselenylchloride with caution, as it can react with moisture and other nucleophiles.
The CAS Registry Mumber 662-46-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,6 and 2 respectively; the second part has 2 digits, 4 and 6 respectively. Calculate Digit Verification of CAS Registry Number 662-46: (5*6)+(4*6)+(3*2)+(2*4)+(1*6)=74 74 % 10 = 4 So 662-46-4 is a valid CAS Registry Number.
