1003001-05-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1003001-05-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,3,0,0 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1003001-05:
(9*1)+(8*0)+(7*0)+(6*3)+(5*0)+(4*0)+(3*1)+(2*0)+(1*5)=35
35 % 10 = 5
So 1003001-05-5 is a valid CAS Registry Number.

Ruthenium-catalyzed cycloaddition of aryl azides and alkynes
Rasmussen, Lars Kyhn,Boren, Brant C.,Fokin, Valery V.
, p. 5337 - 5339 (2008/09/17)
The formation of 1,5-disubstituted 1,2,3-triazoles from aryl azides and alkynes was readily accomplished using [Cp*RuCl]4 catalyst in dimethylformamide. It was also demonstrated that the reaction provided higher yields, cleaner product, and sho
