2-Trimethylsilylmethyl-benzolsulfonsaeure, also known as 2-(trimethylsilyl)ethyl benzenesulfonate, is an organosilicon compound characterized by the presence of a benzene ring with a sulfonate group attached to the 2-position and a trimethylsilylethyl group at the same position. This chemical is a white crystalline solid and is used as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds and as a protecting group in the synthesis of various organic compounds. It is also employed in the preparation of pharmaceuticals and agrochemicals due to its ability to stabilize reactive intermediates and facilitate complex chemical transformations.

Check Digit Verification of cas no

The CAS Registry Mumber 1899-84-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,9 and 9 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1899-84:
(6*1)+(5*8)+(4*9)+(3*9)+(2*8)+(1*4)=129
129 % 10 = 9
So 1899-84-9 is a valid CAS Registry Number.
