Trimethyl-(3,4,4-trifluor-but-3-enyl)-silan, also known as (3,4,4-trifluorobut-3-en-1-yl)trimethylsilane, is an organosilicon compound characterized by its molecular formula C7H11F3Si. This chemical features a trimethylsilyl group (SiMe3) attached to a 3,4,4-trifluorobut-3-enyl moiety, which consists of a butenyl chain with three fluorine atoms at the 3rd, 4th, and 4th carbon positions. The compound is a colorless liquid with a pungent odor and is sensitive to moisture and air. It is primarily used as a reagent in organic synthesis, particularly in the formation of carbon-fluorine bonds and as a protecting group in the synthesis of fluorinated compounds. Due to its reactivity, it is typically handled under an inert atmosphere and stored away from heat and light.

Check Digit Verification of cas no

The CAS Registry Mumber 1645-63-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,4 and 5 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1645-63:
(6*1)+(5*6)+(4*4)+(3*5)+(2*6)+(1*3)=82
82 % 10 = 2
So 1645-63-2 is a valid CAS Registry Number.
