1313758-52-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1313758-52-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,3,7,5 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1313758-52:
(9*1)+(8*3)+(7*1)+(6*3)+(5*7)+(4*5)+(3*8)+(2*5)+(1*2)=149
149 % 10 = 9
So 1313758-52-9 is a valid CAS Registry Number.

Palladium-catalyzed direct arylation of thiophenes bearing SO2R substituents
Bheeter, Charles Beromeo,Bera, Jitendra K.,Doucet, Henri
experimental part, p. 6407 - 6413 (2011/10/04)
The palladium-catalyzed direct arylation of SO2R-substituted thiophene derivatives was found to proceed regioselectively at C5 and in high yields using a variety of aryl bromides and as low as 0.5-0.1 mol % of phosphine-free Pd(OAc)2
