20367-37-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 20367-37-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,3,6 and 7 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 20367-37:
(7*2)+(6*0)+(5*3)+(4*6)+(3*7)+(2*3)+(1*7)=87
87 % 10 = 7
So 20367-37-7 is a valid CAS Registry Number.

Synthesis and photovoltaic characterization of triarylamine-substituted quinoxaline push–pull dyes to improve the performance of dye-sensitized solar cells

Demirak, Kadir,Can, Mustafa,?zsoy, Cihan,Yi?it, Mesude Zeliha,Gültekin, Burak,Demi?, ?erafettin,Zafer, Ceylan

, p. 309 - 322 (2017/07/05)

Novel unsymmetrical organic sensitizers having donor, π-spacer, and anchoring groups were designed and synthesized for dye-sensitized solar cell (DSSC) application. The dyes 3-{4-[7-(4-{bis[4-(hexyl)phenyl]amino} phenyl)-11,12-dibutoxy-1,4,5,8-tetrahydrod

Azolium-linked cyclophanes: Effects of structure, solvent, and counteranions on solution conformation behavior

Baker, Murray V.,Brown, David H.,Heath, Charles H.,Skelton, Brian W.,White, Allan H.,Williams, Charlotte C.

body text, p. 9340 - 9352 (2009/04/07)

(Chemical Equation Presented) This paper describes the synthesis, structural characterization, and solution behavior of some xylyl-linked imidazolium and benzimidazolium cyclophanes decorated with alkyl or alkoxy groups. The addition of alkyl/alkoxy chain

Acetoxylation of 6,7-dialkoxy-substituted 1,4-dihydroquinoxaline-2,3-diones (QXs) using fuming nitric acid in acetic acid: A facile synthesis of 5-acyloxy-6,7-dialkoxy QXs

Zhou, Zhang-Lin,Weber, Eckard,Keana, John F. W.

, p. 7583 - 7586 (2007/10/02)

Treatment of 6,7-dialkoxy-1,4-dihydroquinoxaline-2,3-diones 3 with fuming nitric acid in acetic acid at 25°C resulted in an acetoxylation reaction, giving 5-acetoxy-6,7-dialkoxy-1,4-dihydroquinoxaline-2,3-diones 4 in moderate yields. A mechanism involving ipso attack of nitronium ion as the first step is proposed.
