58311-18-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 58311-18-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,3,1 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 58311-18:
(7*5)+(6*8)+(5*3)+(4*1)+(3*1)+(2*1)+(1*8)=115
115 % 10 = 5
So 58311-18-5 is a valid CAS Registry Number.

Absolute configuration and anticancer activity of taxiresinol and related lignans of Taxus wallichiana

Chattopadhyay, Sunil K.,Kumar, T. R. Santha,Maulik, Prakas R.,Srivastava, Sachin,Garg, Ankur,Sharon, Ashoke,Negi, Arvind S.,Khanuja, Suman Preet S.

, p. 4945 - 4948 (2003)

Absolute configuration of taxiresinol 1, a lignan from the heartwood of Taxus wallichiana has been determined as 8R, 8′R, and 7′R with the help of chemical correlation method and X-ray crystallography. The anticancer activity of taxiresinol 1 and other tw

Identification of lignans by liquid chromatography-electrospray ionization ion-trap mass spectrometry

Eklund, Patrik C.,Backman, M. Josefin,Kronberg, Leif A.,Smeds, Annika I.,Sjoeholm, Rainer E.

, p. 97 - 107 (2008/04/12)

The fragmentation pattern of 30 compounds belonging to different classes of the lignan family was studied by liquid chromatography-electrospray ionization ion-trap mass spectrometry. On the basis of the observed fragmentation patterns, identification of d

Oxidative cyclisation of 3,4-dibenzyltetrahydrofurans using ruthenium tetra(trifluoroacetate)

Ward, Robert S,Hughes, David D

, p. 2057 - 2064 (2007/10/03)

A series of trans-3,4-dibenzyltetrahydrofurans has been synthesised and subjected to oxidative cyclisation using ruthenium tetra(trifluoroacetate), affording dibenzocyclooctadiene lignans belonging to the isostegane series, in high yields. Since no evidence was found for the formation of the corresponding stegane isomers it is assumed that the reactions proceed with complete diastereoselectivity.
