175519-12-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 175519-12-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,5,5,1 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 175519-12:
(8*1)+(7*7)+(6*5)+(5*5)+(4*1)+(3*9)+(2*1)+(1*2)=147
147 % 10 = 7
So 175519-12-7 is a valid CAS Registry Number.

Significant promotional effect of CCl4 on fullerene yield in the graphite arc-discharge reaction

Gao, Fei,Xie, Su-Yuan,Huang, Rong-Bin,Zheng, Lan-Sun

, p. 2676 - 2677 (2003)

Addition of a small quantity (~3%) of CCl4 to the He atmosphere of the graphite arc-discharge reaction revealed a marked increase in fullerene yield.

Stereoselective synthesis of amino-substituted cyclopentafullerenes promoted by magnesium perchlorate/ferric perchlorate

Ma, Wan,Wang, Kun,Huang, Cheng,Wang, Hui-Juan,Li, Fa-Bao,Sun, Rui,Liu, Li,Liu, Chao-Yang,Asiri, Abdullah M.

supporting information, p. 964 - 974 (2020/02/15)

A facile one-step reaction of [60]fullerene with cinnamaldehydes and amines promoted by magnesium perchlorate/ferric perchlorate under air conditions afforded a series of rare amino-substituted cyclopentafullerenes in moderate to good yields. Stereoselectivity was readily achieved. Secondary amines exclusively produced N,N-disubstituted cyclopentafullerenes as cis isomers, while arylamines gave N-monosubstituted cyclopentafullerenes with a preference of cis isomers as major products. N-Monosubstituted cyclopentafullerenes could be further converted into other scarce cyclopentafullerenes in the presence of acid chloride or paraformaldehyde. A possible reaction pathway was proposed to elucidate the formation of amino-substituted cyclopentafullerenes.

Lewis base-catalyzed double nucleophilic substitution reaction of N-tosylaziridinofullerene with thioureas or guanidines

Meng, Qi,Cheng, Jun-Yu,Miao, Chun-Bao,Sun, Xiao-Qiang,Yang, Hai-Tao

, p. 2566 - 2570 (2017/06/13)

Lewis base-catalyzed double nucleophilic substitution reaction of N-tosylaziridinofullerene with thioureas or guanidines affords the fullerothiazolidin-2-imine or fulleroimidazolidin-2-imine derivatives, respectively. In the case of unsymmetrical thiourea
