Urea, trimethyl(trimethylsilyl)-, also known as N,N,N',N'-tetramethyl-N-(trimethylsilyl)urea or TMTU, is an organosilicon compound with the chemical formula C7H21NOSi. It is a colorless, crystalline solid that is soluble in common organic solvents. TMTU is widely used as a protecting group in organic synthesis, particularly for amines, due to its stability and ease of removal under mild conditions. It is also employed as a reagent in the synthesis of various pharmaceuticals and agrochemicals, as well as in the preparation of other organosilicon compounds. The compound is known for its ability to form stable derivatives with primary and secondary amines, which can be selectively deprotected under acidic conditions, making it a valuable tool in the field of chemistry.

65768-03-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 65768-03-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,7,6 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 65768-03:
(7*6)+(6*5)+(5*7)+(4*6)+(3*8)+(2*0)+(1*3)=158
158 % 10 = 8
So 65768-03-8 is a valid CAS Registry Number.
