Check Digit Verification of cas no

The CAS Registry Mumber 1244039-16-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,4,0,3 and 9 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1244039-16:
(9*1)+(8*2)+(7*4)+(6*4)+(5*0)+(4*3)+(3*9)+(2*1)+(1*6)=124
124 % 10 = 4
So 1244039-16-4 is a valid CAS Registry Number.

Au-Catalyzed Cross-Coupling of Arenes via Double C-H Activation

Cambeiro, Xacobe C.,Ahlsten, Nanna,Larrosa, Igor

supporting information, p. 15636 - 15639 (2016/01/09)

The first methodology for Au(I/III)-catalyzed oxidative cross-coupling of arenes via double C-H activation has been developed. The reaction is fully selective for the cross-coupling between electron-rich hetero-/carbocyclic arenes and electron-poor arenes bearing relatively acidic C-H bonds. The inherently high cross-selectivity of the system obviates the need for directing groups or a large excess of one of the coupling partners.

Palladium-catalyzed aerobic dehydrogenative cross-coupling of polyfluoroarenes with thiophenes: Facile access to polyfluoroarene-thiophene structure

He, Chun-Yang,Min, Qiao-Qiao,Zhang, Xingang

experimental part, p. 1335 - 1340 (2012/04/10)

We report a Pd-catalyzed aerobic dehydrogenative cross-coupling of polyfluoroarenes with thiophenes via 2-fold C-H functionalization. The advantages of this reaction are its high reaction efficiency, excellent functional group compatibility, and use of mo
