Check Digit Verification of cas no

The CAS Registry Mumber 1597428-54-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,9,7,4,2 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1597428-54:
(9*1)+(8*5)+(7*9)+(6*7)+(5*4)+(4*2)+(3*8)+(2*5)+(1*4)=220
220 % 10 = 0
So 1597428-54-0 is a valid CAS Registry Number.

Stable 1H-Benzo[c]thio- and 1H-Benzo[c]selenophen-2-ium Tetrafluoroborates: Insight into Electronic Structures, Electrochemical Behavior, and Reactivity

Nagahora, Noriyoshi,Takemoto, Ikue,Fujii, Motomi,Shioji, Kosei,Okuma, Kentaro

, p. 2110 - 2113 (2017/04/27)

The synthesis of 1H-benzo[c]thio- and 1H-benzo[c]selenophen-2-ium tetrafluoroborates by the reaction of triphenylcarbenium tetrafluoroborate with 1-ethylidene-1,3-dihydrobenzo[c]thiophene or 1-ethylidene-1,3-dihydrobenzo[c]selenophene, respectively, is reported. The electronic structure of these novel 1H-benzo[c]chalcogenophenium salts was examined on the basis of their electronic spectra, whereby transitions were assigned in agreement with theoretical calculations. Electrochemical measurements revealed irreversible one-electron reduction waves for these 1H-benzo[c]chalcogenophenium salts.

The First Formation of (1Z)-1-Alkylidene-1H-isobenzofuranium Amides and 1H-Inden-1-ones: Acid-Promoted 5-exo Cyclization and Hydration/Aldol Condensation Reactions of o-Ethynylbenzophenones

supporting information, p. 1423 - 1430 (2015/10/05)

(1Z)-1-(2,2-Dimethylpropylidene)-1H-isobenzofuranium bis(trifluoromethylsulfonyl)amides were synthesized through 5-exo cyclization reactions between sterically encumbered o-alkynylbenzophenones and bis(trifluoromethylsulfonyl)imide (Tf2NH). It
