Tritylnickelchlorid, also known as tritylnickel(II) chloride or tritylnickel dichloride, is a chemical compound with the formula [Ph3C]2[NiCl4]. It is a dark red crystalline solid that is soluble in organic solvents. Tritylnickelchlorid is formed by the reaction of trityl (trityl is a trityl cation, which is a highly resonance-stabilized aryl cation derived from triphenylmethane) with nickel(II) chloride. Tritylnickelchlorid is used as a catalyst in various organic reactions, particularly in the activation of alkynes and the formation of carbon-carbon bonds. It is also employed in the synthesis of certain organic compounds and as a reagent in the preparation of other nickel complexes. Due to its sensitivity to air and moisture, it is typically handled under an inert atmosphere.

Check Digit Verification of cas no

The CAS Registry Mumber 7543-97-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,4 and 3 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 7543-97:
(6*7)+(5*5)+(4*4)+(3*3)+(2*9)+(1*7)=117
117 % 10 = 7
So 7543-97-7 is a valid CAS Registry Number.
