93776-83-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 93776-83-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,7,7 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 93776-83:
(7*9)+(6*3)+(5*7)+(4*7)+(3*6)+(2*8)+(1*3)=181
181 % 10 = 1
So 93776-83-1 is a valid CAS Registry Number.

Synthesis of a thiophene-fused isoindigo derivative: A potential building block for organic semiconductors

Zhao, Na,Qiu, Li,Wang, Xiao,An, Zengjian,Wan, Xiaobo

, p. 1040 - 1044 (2014/02/14)

Thiophene-fused isoindigo (TII) was synthesized from thieno[2,3-f]indol- 6(7H)-one in a one-pot reaction, in which the alkylation, oxidation and condensation were finished in one step. It exhibits better intramolecular charge transfer properties and higher reductive potential compared with isoindigo(II), as evidenced by its optical and electrochemical properties, which shows that it might be used as a building block for n-type or ambipolar OFET materials.
