Check Digit Verification of cas no

The CAS Registry Mumber 20409-51-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,4,0 and 9 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 20409-51:
(7*2)+(6*0)+(5*4)+(4*0)+(3*9)+(2*5)+(1*1)=72
72 % 10 = 2
So 20409-51-2 is a valid CAS Registry Number.

One-Pot Synthesis of Arylketones from Aromatic Acids via Palladium-Catalyzed Suzuki Coupling

Wu, Hongxiang,Xu, Baiping,Li, Yue,Hong, Fengying,Zhu, Dezhao,Jian, Junsheng,Pu, Xiaoer,Zeng, Zhuo

, p. 2987 - 2992 (2016/04/26)

A palladium-catalyzed one-pot procedure for the synthesis of aryl ketones has been developed. Triazine esters when coupled with aryl boronic acids provided aryl ketones in moderate to excellent yields (up to 95%) in the presence of 1 mol % Pd(PPh3)2Cl2 for 30 min. (Chemical Equation Presented).

Ligand-free Pd-catalyzed carbonylative cross-coupling reactions under atmospheric pressure of carbon monoxide: Synthesis of aryl ketones and heteroaromatic ketones

Li, Hongling,Yang, Min,Qi, Yanxing,Xue, Jijun

supporting information; experimental part, p. 2662 - 2667 (2011/06/25)

The carbonylative Suzuki cross-coupling reactions of boronic acids with aryl iodides catalyzed by Pd2(dba)3 as a ligand-free catalyst under atmospheric pressure of carbon monoxide has been firstly developed. Under mild reaction conditions, a broad range of aryl/heteroaryl iodides and aryl/heteroaryl boronic acids were selectively coupled to afford the corresponding diaryl ketones in good to excellent yields at low catalyst loadings (0.05 to 2 mol-%). Moreover, the catalyst can also be recycled. The carbonylative Suzuki cross-coupling reactions of boronic acids with aryl iodides catalyzed by Pd2(dba)3 as a ligand-free catalyst under an atmosphere of carbon monoxide has been developed. A broad range of aryl/heteroaryl iodides and aryl/heteroaryl boronic acids were selectively coupled to afford the corresponding diaryl ketones in good to excellent yields. The catalyst can also be recycled.

Palladium-catalyzed carbonylative coupling of iodonium salts with organostannanes under aqueous conditions: Synthesis of unsymmetrical vinyl and aromatic ketones

Kang, Suk-Ku,Ho, Pil-Su,Yoon, Seok-Keun,Lee, Ju-Cheol,Lee, Kyung-Ju

, p. 823 - 825 (2007/10/03)

The palladium-catalyzed carbonylative coupling reaction of hypervalent iodonium salts with organostannanes was accomplished in the presence of PdCl2 (0.2 mol%) under atmospheric pressure of carbon monoxide at room temperature under aqueous conditions.
