18497-67-1 Usage
General Description
Iron(III) trichloride, also known as ferric chloride, is a chemical compound with the formula FeCl3. It is a dark brown, hygroscopic, and highly soluble solid that is used in a variety of industrial applications, including water treatment, etching and engraving, and as a catalyst in organic synthesis. In its anhydrous form, iron(III) trichloride is a strong Lewis acid, meaning that it readily accepts electron pairs, making it useful in chemical reactions. It can also exist in hydrated forms, including the hexahydrate FeCl3·6H2O and the pentahydrate FeCl3·5H2O, which are often used as catalysts in organic synthesis and as an etchant in PCB manufacturing. Iron(III) trichloride is also utilized as a coagulant in wastewater treatment and as a mordant in dyeing and printing textiles.
Check Digit Verification of cas no
The CAS Registry Mumber 18497-67-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,4,9 and 7 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 18497-67:
(7*1)+(6*8)+(5*4)+(4*9)+(3*7)+(2*6)+(1*7)=151
151 % 10 = 1
So 18497-67-1 is a valid CAS Registry Number.
