3-Trimethylsilylmethyl-benzolsulfonsaeure, also known as 3-(trimethylsilyl)methylbenzenesulfonic acid, is an organosilicon compound characterized by the presence of a trimethylsilyl group (SiMe3) attached to a benzyl moiety, which is further connected to a benzene ring and a sulfonic acid group. This chemical is primarily used as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds and as a protecting group in various chemical reactions. Its unique structure allows for selective reactions and controlled functional group transformations, making it a valuable tool in the field of organic chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 1899-87-2 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 7 respectively.
Calculate Digit Verification of CAS Registry Number 1899-87:
(6*1)+(5*8)+(4*9)+(3*9)+(2*8)+(1*7)=132
132 % 10 = 2
So 1899-87-2 is a valid CAS Registry Number.
