Check Digit Verification of cas no

The CAS Registry Mumber 151872-45-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,1,8,7 and 2 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 151872-45:
(8*1)+(7*5)+(6*1)+(5*8)+(4*7)+(3*2)+(2*4)+(1*5)=136
136 % 10 = 6
So 151872-45-6 is a valid CAS Registry Number.

An efficient route to the synthesis of symmetric and asymmetric diastereomerically pure fullerene triads

Lebedeva, Maria A.,Chamberlain, Thomas W.,Schr?der, Martin,Khlobystov, Andrei N.

experimental part, p. 4976 - 4985 (2012/08/27)

A new synthetic route based on the stepwise functionalisation of fullerene cages allows the facile formation of linear, diastereomerically pure triads incorporating two different fullerene cages linked by an organic spacer group. The critical coupling step of two fullerene cages via activation by N,N′-dicyclohexylcarbodiimide was systematically investigated to reveal that the yield of the coupling is maximised in o-dichlorobenzene at high concentrations of the reactant fullerene nucleophile, while in more polar solvents or at lower concentrations of reactants the formation of unwanted side-products (such as guanidine-, N-acylurea- and anhydride-functionalised fullerenes) is favoured. The resultant triads possess an atypically good solubility for this class of compound, which enabled full detailed characterisation by 1H and 13C NMR, IR and UV-vis spectroscopies and by MALDI-TOF mass spectrometry.

Hydrogen bond-assembled fullerene molecular shuttle

Da Ros, Tatiana,Guldi, Dirk M.,Morales, Angeles Farran,Leigh, David A.,Prato, Maurizio,Turco, Riccardo

, p. 689 - 691 (2007/10/03)

(Figure presented) A novel [2]rotaxane has been prepared in which fullerene C60 behaves as both a stopper and a photoactive unit. The amphiphilic nature of the rotaxane thread can be used to shuttle the macrocycle from close to the fullerene sp
