Check Digit Verification of cas no

The CAS Registry Mumber 1268524-63-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,8,5,2 and 4 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1268524-63:
(9*1)+(8*2)+(7*6)+(6*8)+(5*5)+(4*2)+(3*4)+(2*6)+(1*3)=175
175 % 10 = 5
So 1268524-63-5 is a valid CAS Registry Number.

A copper(I) isonitrile complex as a heterogeneous catalyst for azide-alkyne cycloaddition in water

Liu, Meina,Reiser, Oliver

, p. 1102 - 1105 (2011/04/24)

A structurally well-defined copper(I) isonitrile complex is shown to be an efficient, heterogeneous catalyst for the Huisgen azide-alkyne 1,3-dipolar cycloaddition under mild conditions in water. Notably, this catalyst can also be utilized in a three-component reaction of halides, sodium azide and alkynes to form 1,4-disubstituted 1,2,3-triazoles in high yields. Furthermore, it can be readily recovered by precipitation and filtration and recycled for at least five runs without significant loss of activity.(Figure Presented)
