18937-91-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 18937-91-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,9,3 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 18937-91:
(7*1)+(6*8)+(5*9)+(4*3)+(3*7)+(2*9)+(1*1)=152
152 % 10 = 2
So 18937-91-2 is a valid CAS Registry Number.

Visible-Light-Promoted, Catalyst-Free Gomberg-Bachmann Reaction: Synthesis of Biaryls

Lee, Juyoung,Hong, Boseok,Lee, Anna

, p. 9297 - 9306 (2019/08/12)

Biaryls were synthesized via a novel visible-light-promoted Gomberg-Bachmann reaction that does not require a photosensitizer or any metal reagents. The formation of an electron donor-acceptor complex between aryl diazonium salts and pyridine allows, under visible-light irradiation, the synthesis of biaryls in moderate-to-high yields.

An efficient indenyl-derived phosphine ligand for the Suzuki-Miyaura coupling of sterically hindered aryl halides

Liu, Yan,Peng, Hui,Yuan, Jia,Yan, Meng-Qi,Luo, Xue,Wu, Qing-Guo,Liu, Sheng-Hua,Chen, Jian,Yu, Guang-Ao

supporting information, p. 4664 - 4668 (2016/06/09)

An air-stable aryl substituted indenyl phosphine used in combination with Pd(OAc)2 provides a highly efficient catalyst for the Suzuki-Miyaura cross-coupling reaction of sterically hindered aryl halides with aryl boronic acids.
