Trimethylsilyl dithiobenzoate, also known as TMS-dithiobenzoate, is a chemical compound with the molecular formula C11H14OS2Si. It is a colorless to pale yellow liquid that is soluble in organic solvents. Trimethylsilyl dithiobenzoate is widely used as a protecting group in organic synthesis, particularly for thiols, due to its stability and ease of removal under mild conditions. The trimethylsilyl group (TMS) provides a stable and easily removable protecting group, while the dithiobenzoate moiety offers a strong electron-withdrawing effect, which can influence the reactivity of the thiol group. TMS-dithiobenzoate is also used in the synthesis of various pharmaceuticals and agrochemicals, as well as in the preparation of other organosulfur compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 42967-57-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,9,6 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 42967-57:
(7*4)+(6*2)+(5*9)+(4*6)+(3*7)+(2*5)+(1*7)=147
147 % 10 = 7
So 42967-57-7 is a valid CAS Registry Number.
