Triphenylmethyl-triphenylsilane, also known as hexaphenylsilanedimethyl, is a complex organosilicon compound with the chemical formula (C6H5)3Si-C(C6H5)3. It is a white crystalline solid that is highly sensitive to air and moisture, and it is insoluble in water. triphenylmethyl-triphenylsilane is formed by the combination of a triphenylmethyl group (C6H5)3C- and a triphenylsilyl group (C6H5)3Si-. Triphenylmethyl-triphenylsilane is an important intermediate in the synthesis of various organosilicon compounds and is used in the preparation of silyl ethers, silyl enol ethers, and other organosilicon reagents. Due to its sensitivity to air and moisture, it is typically handled under an inert atmosphere or in a glovebox.

Check Digit Verification of cas no

The CAS Registry Mumber 18843-83-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,8,4 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 18843-83:
(7*1)+(6*8)+(5*8)+(4*4)+(3*3)+(2*8)+(1*3)=139
139 % 10 = 9
So 18843-83-9 is a valid CAS Registry Number.
