Trimethylsilyl (2,4,5-trichlorophenoxy)acetate is a chemical compound with the molecular formula C11H13Cl3O3Si. It is a derivative of acetic acid, where the hydroxyl group is replaced by a trimethylsilyl group and a 2,4,5-trichlorophenoxy group. trimethylsilyl (2,4,5-trichlorophenoxy)acetate is known for its use as a protecting group in organic synthesis, particularly for alcohols and phenols, due to its stability and ease of removal under mild conditions. The trimethylsilyl group provides a stable, electron-donating protecting group that can be selectively removed using fluoride ions, making it a valuable tool in the synthesis of complex organic molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 34113-75-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,1,1 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 34113-75:
(7*3)+(6*4)+(5*1)+(4*1)+(3*3)+(2*7)+(1*5)=82
82 % 10 = 2
So 34113-75-2 is a valid CAS Registry Number.
