156551-17-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 156551-17-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,5,5 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 156551-17:
(8*1)+(7*5)+(6*6)+(5*5)+(4*5)+(3*1)+(2*1)+(1*7)=136
136 % 10 = 6
So 156551-17-6 is a valid CAS Registry Number.

Silylmethylations of C60 with Grignard Reagents: Selective Synthesis of HC60CH2SiMe2Y and C60(CH2SiMe2Y)2 with Selection of Solvents

Nagashima, Hideo,Terasaki, Hiroshi,Kimura, Eiji,Nakajima, Katsumasa,Itoh, Kenji

, p. 1246 - 1248 (1994)

Addition reactions of Me2SiYCH2MgCl (1) to C60 provided two products, HC60CH2SiYMe2 (2) and 2C60 (3) (Y = Me, H, CH=CH2, Ph, O-iPr).Selective preparation of either 2 or 3 was accomplished by selection of the solvent; 2 was formed in THF, wherea

Regioselective synthesis of 1,4-di(organo)[60]fullerenes through DMF-assisted monoaddition of silylmethyl Grignard reagents and subsequent alkylation reaction

Matsuo, Yutaka,Iwashita, Akihiko,Abe, Yoko,Li, Chang-Zhi,Matsuo, Keiko,Hashiguchi, Masahiko,Nakamura, Eiichi

supporting information; experimental part, p. 15429 - 15436 (2009/03/11)

Monoaddition of Grignard reagents, in particular tri(organo) silylmethylmagnesium chlorides, to [60]fullerene took place smoothly in the presence of dimethylformamide to produce (organo)(hydro)[60]fullerenes, C 60C)R1H, in good yield
