33240-61-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 33240-61-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,2,4 and 0 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 33240-61:
(7*3)+(6*3)+(5*2)+(4*4)+(3*0)+(2*6)+(1*1)=78
78 % 10 = 8
So 33240-61-8 is a valid CAS Registry Number.

Preparation and characterization of persistent maltose-conjugated triphenylmethyl radicals

Mesa, Juan Antonio,Velazquez-Palenzuela, Amado,Brillas, Enric,Coll, Josep,Torres, Josep Lluis,Julia, Luis

, p. 1081 - 1086 (2012)

The condensation reaction of d-maltose to free radicals of the series of tris(2,4,6-trichlorophenyl)methyl (TTM) and tris(perchlorophenyl)methyl (PTM) has been described for the first time. The new persistent radicals 1 and 2 are very stable and have been

Chemical Modification toward Long Spin Lifetimes in Organic Conjugated Radicals

Dai, Ya-Zhong,Dong, Bo-Wei,Kao, Yi,Wang, Zi-Yuan,Un, Hio-Ieng,Liu, Zheng,Lin, Zhi-Jun,Li, Liang,Xie, Fang-Bai,Lu, Yang,Xu, Mei-Xing,Lei, Ting,Sun, Yu-Jie,Wang, Jie-Yu,Gao, Song,Jiang, Shang-Da,Pei, Jian

, p. 2972 - 2977 (2018/09/25)

Organic semiconductors for spin-based devices require long spin relaxation times. Understanding their spin relaxation mechanisms is critical to organic spintronic devices and applications for quantum information processing. However, reports on the spin re

Photochemistry of Stable Free Radicals: The Photolysis of Perchlorotriphenylmethyl Radicals

Fox, Marye Anne,Gaillard, Elizabeth,Chen, Chia-Chung

, p. 7088 - 7094 (2007/10/02)

The excitation of perchlorotriphenylmethyl radical (PTM) at 532 nm leads to an excited doublet, 2PTM* (τ = 7 ns).The lifetime of this state is insensitive to oxygen, electron acceptors, and hydrogen-donating solvents.Electron donors
