Bromo-trimethylsilanyl-acetyl bromide, also known as (bromoacetyl)trimethylsilane, is a chemical compound with the molecular formula C4H9BrOSi. It is a colorless liquid that is soluble in organic solvents and is commonly used as a reagent in organic synthesis. Bromo-trimethylsilanyl-acetyl bromide is particularly useful for the protection of aldehydes and ketones, as it forms a stable silyl ether upon reaction, which can be easily removed under mild conditions. It is also employed in the synthesis of various pharmaceuticals and agrochemicals due to its ability to introduce bromine atoms into organic molecules. The compound should be handled with care, as it is corrosive and toxic, and it is important to follow proper safety protocols when working with it.

Check Digit Verification of cas no

The CAS Registry Mumber 4189-75-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,8 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4189-75:
(6*4)+(5*1)+(4*8)+(3*9)+(2*7)+(1*5)=107
107 % 10 = 7
So 4189-75-7 is a valid CAS Registry Number.
