Check Digit Verification of cas no
The CAS Registry Mumber 118688-56-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,6,8 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 118688-56:
(8*1)+(7*1)+(6*8)+(5*6)+(4*8)+(3*8)+(2*5)+(1*6)=165
165 % 10 = 5
So 118688-56-5 is a valid CAS Registry Number.

Gold and palladium combined for the Sonogashira coupling of aryl and heteroaryl halides

, p. 817 - 829 (2013/04/10)
A highly efficient gold and palladium combined methodology for the Sonogashira coupling of a wide array of electronically and structurally diverse aryl and heteroaryl halides is described. The orthogonal reactivity of the two metals shows high selectivity and extreme functional group tolerance in Sonogashira coupling. A brief mechanistic study reveals that the gold acetylide intermediate enters into the palladium catalytic cycle at the transmetalation step. Georg Thieme Verlag Stuttgart.New York.
Palladium-catalyzed copper-free sonogashira coupling reaction in water and acetone

An efficient palladium-catalyzed copper-free Sonogashira reaction in water and acetone has been developed under mild conditions. The results showed that the aryl iodides could carry out the cross-coupling reaction with a variety of terminal alkynes in high yields in water-acetone in the absence of amine, copper(I) salts, or phosphine ligands at 60°C for one hour, and good yields were obtained for aryl bromides at 60°C for 12-24 hours in the presence of triphenylphosphine and piperidine. The method could be used to synthesize polyethynyl aromatic compounds in a one-pot reaction. Georg Thieme Verlag Stuttgart.
