Check Digit Verification of cas no

The CAS Registry Mumber 132554-37-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,5,5 and 4 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 132554-37:
(8*1)+(7*3)+(6*2)+(5*5)+(4*5)+(3*4)+(2*3)+(1*7)=111
111 % 10 = 1
So 132554-37-1 is a valid CAS Registry Number.

In Situ Preparation of Palladium Nanoparticles for C-2 Selective Arylation of Indoles in Agro-Waste Extract Based Mixed Solvents

Jin, Weiwei,Liu, Chenjiang,Liu, Tianxiang,Sun, Yajun,Wang, Bin,Wang, Rui,Xia, Yu,Zhang, Yonghong

supporting information, p. 2470 - 2473 (2021/06/25)

An efficient and practical method for the in situ generation of palladium nanoparticles was successfully established in a water extract of pomelo peel ash. The produced palladium nanoparticles were characterized by energy-dispersive X-ray spectroscopy elemental mapping, field emission scanning electron microscopy, high-resolution transmission electron microscope, X-ray powder diffraction, and showed high catalytic activity for selective C-2 arylation of indoles. A series of 2-arylindoles were smoothly installed in moderate to good yields through the direct palladium-catalyzed cross-coupling reactions of indoles and iodoarenes without external ligand, base, oxidant, and preinstallation directing group.

A Three-Component Strategy for Benzoselenophene Synthesis under Metal-Free Conditions Using Selenium Powder

Ni, Penghui,Tan, Jing,Zhao, Wenqi,Huang, Huawen,Xiao, Fuhong,Deng, Guo-Jun

, p. 3518 - 3522 (2019/05/24)

An efficient three-component benzoselenophenes formation has been developed from substituted indoles, acetophenones, and selenium powder under metal-free conditions. 2-Aryl indoles played an important role to promote benzoselenophene formation from acetophenone derivatives and selenium powder. One C-C and two C-Se bonds were selectively formed to provide 40 new benzoselenophenes in good yields.

Pd(OAc)2-catalyzed regioselective arylation of indoles with arylsiloxane in acidic medium

Liang, Zunjun,Yao, Bangben,Zhang, Yuhong

supporting information; scheme or table, p. 3185 - 3187 (2010/08/20)

(Figure Presented) Mild conditions have been developed to achieve a Pd(OAc)2-catalyzed cross-coupling between indoles and arylsiloxanes in the presence of TBAF and Ag2O in acidic medium. Electron-deficient arylsiloxanes presented high efficiency in this system to give the arylated indoles in excellent yields.
