175414-74-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 175414-74-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,5,4,1 and 4 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 175414-74:
(8*1)+(7*7)+(6*5)+(5*4)+(4*1)+(3*4)+(2*7)+(1*4)=141
141 % 10 = 1
So 175414-74-1 is a valid CAS Registry Number.

Laser deposition of carbon clusters on surfaces: A new approach to the study of Fullerenes

Meijer, Gerard,Bethune, Donald S.

, p. 7800 - 7802 (1990)

We have accumulated large pure carbon clusters (Fullerenes) on a surface.These clusters were produced by laser vaporization of graphite in a static rare-gas atmosphere.Their presence on the surface was confirmed by an isotope scrambling experiment using a laser-desorption/laser-ionization mass spectrometric detection scheme.

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.

Lu2@C2n (2n = 82, 84, 86): Crystallographic Evidence of Direct Lu-Lu Bonding between Two Divalent Lutetium Ions Inside Fullerene Cages

Shen, Wangqiang,Bao, Lipiao,Wu, Yongbo,Pan, Changwang,Zhao, Shasha,Fang, Hongyun,Xie, Yunpeng,Jin, Peng,Peng, Ping,Li, Fang-Fang,Lu, Xing

supporting information, p. 9979 - 9984 (2017/08/02)

Although most of the M2C2n-type metallofullerenes (EMFs) tend to form carbide cluster EMFs, we report herein that Lu-containing EMFs Lu2C2n (2n = 82, 84, 86) are actually dimetallofullerenes (di-EMFs), namely, Lu2@Cs(6)-C82, Lu2@C3v(8)-C82, Lu2@D2d(23)-C84, and Lu2@C2v(9)-C86. Unambiguous X-ray results demonstrate the formation of a Lu-Lu single bond between two lutetium ions which transfers four electrons in total to the fullerene cages, thus resulting in a formal divalent state for each Lu ion. Population analysis indicates that each Lu atom formally donates a 5d electron and a 6s electron to the cage with the remaining 6s electron shared with the other Lu atom to form a Lu-Lu single bond so that only four electrons are transferred to the fullerene cages with the formal divalent valence for each lutetium ion. Accordingly, we confirmed both experimentally and theoretically that the dominating formation of di-EMFs is thermodynamically very favorable for Lu2C2n isomers.
