Isothiocyanato-triphenoxy-silane, also known as (isothiocyanato)triphenoxysilane or Si(OC6H5)3-NCS, is an organosilicon compound characterized by a silicon atom bonded to three phenoxy groups and an isothiocyanate group. This colorless to pale yellow liquid is a valuable reagent in the synthesis of various organosilicon compounds and materials, particularly in the field of silane coupling agents. It is used to modify surfaces, improve adhesion, and enhance the properties of materials such as polymers, ceramics, and glasses. The compound is sensitive to moisture and air, and it is typically stored under an inert atmosphere to prevent decomposition. Its unique structure allows it to form strong covalent bonds with inorganic surfaces and organic polymers, making it a versatile tool in material science and chemical research.

Check Digit Verification of cas no

The CAS Registry Mumber 4667-55-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,6 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4667-55:
(6*4)+(5*6)+(4*6)+(3*7)+(2*5)+(1*5)=114
114 % 10 = 4
So 4667-55-4 is a valid CAS Registry Number.
