68828-00-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 68828-00-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,8,2 and 8 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 68828-00:
(7*6)+(6*8)+(5*8)+(4*2)+(3*8)+(2*0)+(1*0)=162
162 % 10 = 2
So 68828-00-2 is a valid CAS Registry Number.

A rapid and efficient method for the synthesis of 14H-dibenzo[7α.j] xanthenes, aryl-5H-dibenzo [b.i]xanthene-5,7,12,14-(13H)-tetraone and 1,8-dioxo-octahydroxanthenes by acidic ionic liquid

Rahmati, Abbas

, p. 761 - 764 (2010)

Various xanthenes have been synthesized by the condensation of β-naphthol, 2-hydroxynaphthalene-1,4-dione or dimedone with various aldehydes in the presence of trifluoroacetic acid as catalyst in 1,1,3,3-N,N,N',N'-tetramethylguanidinium trifluoroacetate (

Br?nsted acidic ionic liquid as an efficient and reusable catalyst for synthesis of 14-aryl-or 14-alkyl-14 H-dibenzo[a,j]xanthenes under solvent-free conditions

Hajipour, Abdol R.,Ghayeb, Yosof,Sheikhan, Nafisehsadat,Ruoho, Arnold E.

experimental part, p. 741 - 744 (2010/06/13)

A mild and efficient method has been developed for the preparation of 14-aryl-or 14-alkyl-14H-dibenzo[a,j]xanthenes from one-pot condensation of aldehydes with 2-naphthol using catalytic amount of Br?nsted acidic ionic liquid ([TEBSA][HSO) under thermal s

Facile and efficient synthesis of 14-alkyl- or aryl-14-H-dibenzo[a,j] xanthenes using sulfonyl-functionalized ionic liquids

Kumari, Pratibha,Yathindranath, Vinith,Chauhan

, p. 637 - 648 (2008/04/12)

An efficient, simple, and rapid synthesis of 14-alkyl-or aryl-14-H-dibenzo[a,j]xanthenes is reported by one-pot condensation of 2-naphthol with alkyl or aryl aldehydes in the presence of sulfonyl- functionalized acidic ionic liquids at 125°C. Copyright Ta
