Triphenylsilyl-diphenylphosphinthioyl-acetylen is a complex organic compound characterized by its unique structure, which consists of a central acetylenic carbon-carbon triple bond (C≡C) flanked by a triphenylsilyl group (Ph3Si) and a diphenylphosphinothioyl group (Ph2P(S)-). The triphenylsilyl group is an electron-donating aryl group that can stabilize the molecule, while the diphenylphosphinothioyl group acts as a chelating ligand, potentially forming coordination complexes with metal ions. Triphenylsilyl-diphenylphosphinthioyl-acetylen is of interest in the field of organosilicon chemistry and organophosphorus chemistry, as it combines the properties of both silicon and phosphorus-containing compounds. It may have applications in the synthesis of advanced materials, catalysis, and as a precursor in the preparation of other complex molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 21038-03-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,0,3 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 21038-03:
(7*2)+(6*1)+(5*0)+(4*3)+(3*8)+(2*0)+(1*3)=59
59 % 10 = 9
So 21038-03-9 is a valid CAS Registry Number.
