Tris-triaethylsilyl-antimon, also known as triethylsilylantimony triethyl, is a chemical compound with the formula (C2H5)3SiSb(C2H5)3. It is a colorless, viscous liquid that is sensitive to air and moisture. Tris-triaethylsilyl-antimon is a derivative of antimony, with three triethylsilyl groups (C2H5)3Si attached to the antimony atom. Tris-triaethylsilyl-antimon is primarily used as a reagent in organic synthesis, particularly in the formation of organoantimony compounds. It is also employed as a reducing agent and a coupling agent in various chemical reactions. Due to its sensitivity to air and moisture, it is essential to handle Tris-triaethylsilyl-antimon under an inert atmosphere, such as nitrogen or argon, to prevent unwanted side reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 4631-57-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,3 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4631-57:
(6*4)+(5*6)+(4*3)+(3*1)+(2*5)+(1*7)=86
86 % 10 = 6
So 4631-57-6 is a valid CAS Registry Number.
