Check Digit Verification of cas no

The CAS Registry Mumber 1309448-77-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,4,4 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1309448-77:
(9*1)+(8*3)+(7*0)+(6*9)+(5*4)+(4*4)+(3*8)+(2*7)+(1*7)=168
168 % 10 = 8
So 1309448-77-8 is a valid CAS Registry Number.

Toluene derivatives as simple coupling precursors for cascade palladium-catalyzed oxidative C-H bond acylation of acetanilides

Wu, Yinuo,Choy, Pui Ying,Mao, Fei,Kwong, Fuk Yee

supporting information, p. 689 - 691 (2013/02/25)

A palladium-catalyzed cascade cross-coupling of acetanilide and toluene for the synthesis of ortho-acylacetanilide is described. Toluene derivatives can act as effective acyl precursors (upon sp3-C-H bond oxidation by a Pd/TBHP system) in the oxidative coupling between two C-H bonds. This dehydrogenative Pd-catalyzed ortho-acylation proceeds under mild reaction conditions.

Palladium-catalyzed oxidative C-H bond coupling of steered acetanilides and aldehydes: A facile access to ortho -acylacetanilides

Wu, Yinuo,Li, Baozhu,Mao, Fei,Li, Xingshu,Kwong, Fuk Yee

, p. 3258 - 3261 (2011/08/05)

A palladium-catalyzed oxidative C-H bond functionalization/ortho-acylation of acetanilides using easily accessible aldehyde as the acyl source is described. In the presence of a Pd(TFA)2 catalyst and tert-butylhydroperoxide at 90 °C in general, an array of ortho-acylacetanilides can be afforded in good yields.
