N-Methyl-N'-phenyl-N,N'-bis(trimethylsilyl)harnstoff, also known as N-Methyl-N'-phenyl-N,N'-bis(trimethylsilyl)urea, is a complex organic compound with the chemical formula C13H28N2OSi2. It is a white crystalline solid that is soluble in common organic solvents. N-Methyl-N'-phenyl-N,N'-bis(trimethylsilyl)harnstoff is characterized by the presence of a urea group (-NH-CO-NH-), with one nitrogen atom substituted by a methyl group (-CH3) and the other by a phenyl group (C6H5). Additionally, both nitrogen atoms are connected to trimethylsilyl groups (-Si(CH3)3), which contribute to the compound's stability and reactivity. N-Methyl-N'-phenyl-N,N'-bis(trimethylsilyl)harnstoff is primarily used as a reagent in organic synthesis, particularly in the formation of carbon-nitrogen bonds and as a protecting group for amines. Its unique structure allows for a range of applications in the synthesis of pharmaceuticals, agrochemicals, and other specialty chemicals.

Check Digit Verification of cas no

The CAS Registry Mumber 1028-22-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,2 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1028-22:
(6*1)+(5*0)+(4*2)+(3*8)+(2*2)+(1*2)=44
44 % 10 = 4
So 1028-22-4 is a valid CAS Registry Number.
