Trimethylene selenide, also known as 1,3-diselenacyclohexane, is a chemical compound with the formula C3H6Se2. It is a colorless liquid at room temperature and has a garlic-like odor. This organoselenium compound is formed by the reaction of 1,3-dibromopropane with sodium selenide in anhydrous ethanol. Trimethylene selenide is an important intermediate in the synthesis of various organoselenium compounds, which have applications in pharmaceuticals, agrochemicals, and materials science. It is also used as a reagent in organic synthesis, particularly in the formation of carbon-selenium bonds. Due to its reactivity and potential toxicity, it is essential to handle trimethylene selenide with proper safety precautions.

287-28-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 287-28-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,8 and 7 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 287-28:
(5*2)+(4*8)+(3*7)+(2*2)+(1*8)=75
75 % 10 = 5
So 287-28-5 is a valid CAS Registry Number.
