Triphenylisothiocyanatosilane, also known as triphenylsilylisothiocyanate, is an organosilicon compound with the chemical formula (C6H5)3SiNCS. It is a colorless, crystalline solid that is sensitive to air and moisture. triphenylisothiocyanatosilane is formed by the reaction of triphenylchlorosilane with potassium thiocyanate in anhydrous ether. Triphenylisothiocyanatosilane is used as a reagent in organic synthesis, particularly in the preparation of various organosilicon compounds and as a protecting group in the synthesis of certain organic molecules. Due to its sensitivity to air and moisture, it is essential to handle triphenylisothiocyanatosilane under an inert atmosphere or in a glove box.

Check Digit Verification of cas no

The CAS Registry Mumber 1929-48-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,2 and 9 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1929-48:
(6*1)+(5*9)+(4*2)+(3*9)+(2*4)+(1*8)=102
102 % 10 = 2
So 1929-48-2 is a valid CAS Registry Number.

ULTRAVIOLET SPECTROSCOPIC INVESTIGATION OF ISOCYANATO- AND ISOTHIOCYANATO SILANES CONTAINING PHENYL- AND METHYL GROUPS

Veszpremi, Tamas,Barta, Istvan,Nagy, Jozsef

, p. 243 - 250 (2007/10/02)

The members of the series R(n)Si(NCO)(4-n) and R(n)Si(NCS)(4-n), where R = -CH3 and -C6H5, were prepared, their ultraviolet spectra recorded and the observed bands assigned.The spectra were compared to those of halogeno derivatives.The similarity of halogen- and pseudohalogeno-groups and difference between the effect of methyl- and phenyl-groups were studied.
