143746-74-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 143746-74-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,7,4 and 6 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 143746-74:
(8*1)+(7*4)+(6*3)+(5*7)+(4*4)+(3*6)+(2*7)+(1*4)=141
141 % 10 = 1
So 143746-74-1 is a valid CAS Registry Number.

Novel ?-Extended Thiophene-Fused Electron Acceptors for Organic Metals

Cruz, Pilar de la,Martin, Nazario,Miguel, Fuencisla,Seoane, Carlos,Albert, Armando,et al.

, p. 6192 - 6198 (2007/10/02)

Novel ?-extended thiophene-fused TCNQ-type and DCNQI-type acceptors have been synthesized from the corresonding quinones by reaction with Lehnert's reagent and bis(trimetylsilyl)carbodiimide (BTC), respectively.Additionally, an example of the little-known hybrid TCNQ-DCNQI-type acceptor has also been obtained.The cyclic voltammetric data of the novel acceptors reveal two different behaviours for these molecules.The TCNQ-type derivatives exhibit a two-electron single-wave reduction to the dianion, as confirmed by controlled potential coulometry analysis.The DCNQI-type derivatives display two reduction waves to the corresponding radical anion and dianion.The same behaviour is shown by the hybrid TCNQ-DCNQI derivative.The acceptor ability is related to molecular planarity, and a comparative crystallographic study involving TCNQ-type and DCNQI-type derivatives (6a, 7a, and 8a) has been performed.
