Check Digit Verification of cas no

The CAS Registry Mumber 69618-12-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,6,1 and 8 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 69618-12:
(7*6)+(6*9)+(5*6)+(4*1)+(3*8)+(2*1)+(1*2)=158
158 % 10 = 8
So 69618-12-8 is a valid CAS Registry Number.

Rapid pseudo five-component synthesis of intensively blue luminescent 2,5-di(hetero)arylfurans via a Sonogashira-Glaser cyclization sequence

Klukas, Fabian,Grunwald, Alexander,Menschel, Franziska,Mueller, Thomas J. J.

, p. 672 - 679 (2014/04/17)

2,5-Di(hetero)arylfurans are readily accessible in a pseudo five-component reaction via a Sonogashira-Glaser coupling sequence followed by a superbase-mediated (KOH/DMSO) cyclization in a consecutive one-pot fashion. Besides the straightforward synthesis of natural products and biologically active molecules all representatives are particularly interesting due to their bright blue luminescence with remarkably high quantum yields. The electronic structure of the title compounds is additionally studied with DFT computations.

2,4-BIS-(2'-METHOXY-5'-METHYLPHENYL)-FURAN, A RARE TYPE OF COMPOUND FROM BERBERIS UMBRELLATA

Masood, M.,Tiwari, K. P.

, p. 295 - 296 (2007/10/02)

Key Word Index - Berberis umbrellata; Berberidaceae; 2,5-bis-(2'-methoxy-5'-methylphenyl)-furan. The ethanolic extract of the root of Berberis umbrellata yielded 2,5-bis-(2'-methoxy-5'-methylphenyl)-furan which has not been previously isolated from a natu
