α-(Trimethylsilyl)vinyl alcohol, also known as (trimethylsilyl)ethenol, is an organosilicon compound with the chemical formula (CH3)3SiCH=CHOH. It is a colorless liquid that is sensitive to air and moisture, and it is commonly used as a protecting group in organic synthesis. The molecule features a vinyl group (C=C) bonded to a hydroxyl group (OH), with a trimethylsilyl group (Si(CH3)3) attached to the carbon atom adjacent to the vinyl group. This unique structure allows it to participate in various chemical reactions, such as hydrosilation and cross-metathesis, making it a valuable intermediate in the synthesis of complex organic molecules. Due to its reactivity, it is typically stored and handled under an inert atmosphere to prevent unwanted side reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 80631-08-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,6,3 and 1 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 80631-08:
(7*8)+(6*0)+(5*6)+(4*3)+(3*1)+(2*0)+(1*8)=109
109 % 10 = 9
So 80631-08-9 is a valid CAS Registry Number.
