74134-56-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 74134-56-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,1,3 and 4 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 74134-56:
(7*7)+(6*4)+(5*1)+(4*3)+(3*4)+(2*5)+(1*6)=118
118 % 10 = 8
So 74134-56-8 is a valid CAS Registry Number.

SYNTHESIS AND CHARACTERIZATION OF ALKYL-, HALO- AND HETEROSUBSTITUTED DERIVATIVES OF THE POTENT PHOTOTOXIN &α-TERTHIENYL

Eachern, Anita Mac,Soucy, Chantal,Leitch, Leonard C.,Arnason, John T.,Morand, Peter

, p. 2403 - 2412 (2007/10/02)

A number of derivatives of α-terthienyl were prepared including a series of naturally occurring compounds.A description of the syntheses of some new compounds, including 5-iodo, 5,5''-diiodo, 5,5''-diformyl, 5,5''-di-tert butyl, 5-tert-butyl, 5-tert-butoxy, 5-trimethylsilyl, 5-thiomethyl, 5,5''-dithiomethyl and 5-carboxyl-5''-(trimethylsilyl)-2,2':5',2''-terthienyl is also given.An analysis of the 1H NMR data of the derivatives is presented.

5-(2,3-DIPHENYLCYCLOPROPENYLIDENE)-2(5H)-THIOPHENONE CHARACTERIZATION OF A THIOPHENE-INSERTED TYPE COMPOUND OF DIPHENYLCYCLOPROPENONE

Takahashi, Kazuko,Nishijima, Kazumi,Takase, Kahei,Katagiri, Shigeyoshi

, p. 205 - 208 (2007/10/02)

The title compound 6 has been synthesized and the effect of cyclic ?-system insertion into diphenylcyclopropenone 1 has been discussed.The distribution of positive charge over the 3-membd. ring and phenyl groups slightly predominates in 6 than in parent annulenone 1, in contrast to 5-cycloheptatrienylidene-2(5H)-tiophenone 5 whose 7-membd. ring is more olefinic than parent tropone 2.Electronic spectrum of 6 exhibits a broad absorption band having a C-T character.
