1226571-79-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1226571-79-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,6,5,7 and 1 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1226571-79:
(9*1)+(8*2)+(7*2)+(6*6)+(5*5)+(4*7)+(3*1)+(2*7)+(1*9)=154
154 % 10 = 4
So 1226571-79-4 is a valid CAS Registry Number.

One-pot procedure for the synthesis of unsymmetrical diarylalkynes
Severin, Rene,Reimer, Jessica,Doye, Sven
, p. 3518 - 3521 (2010)
Unsymmetrical diarylalkynes are accessible by a one-pot procedure from two different aryl halides and (trimethylsilyl)acetylene. The three-component coupling is initialized by a Pd/Cu-catalyzed Sonogashira coupling of an aryl halide with (trimethylsilyl)a
