Check Digit Verification of cas no

The CAS Registry Mumber 1356445-70-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,6,4,4 and 5 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1356445-70:
(9*1)+(8*3)+(7*5)+(6*6)+(5*4)+(4*4)+(3*5)+(2*7)+(1*0)=169
169 % 10 = 9
So 1356445-70-9 is a valid CAS Registry Number.

Synthesis of self-threading bithiophenes and their structure-property relationships regarding cyclic side-chains with atomic precision

Ouchi, Yuki,Sugiyasu, Kazunori,Ogi, Soichiro,Sato, Akira,Takeuchi, Masayuki

, p. 75 - 84 (2012/04/04)

We have recently reported a self-threading polythiophene as a new family of insulated molecular wires. Herein, we focused on the structure-property relationships of the unique three-dimensional architecture of the monomer. We have synthesized nine self-threading bithiophene monomers that have cyclic side-chains of different size and flexibility: i.e., 21-, 22-, 23-, 24-, 26-, and 30-membered rings composed of paraffinic, olefinic, or alkynic chains. To investigate their structure-property relationships, 1H NMR spectroscopy, UV absorption, and fluorescence spectroscopy measurements were conducted. We found that cyclic side-chains define the movable range of the dihedral angle of the bithiophene backbone, thereby affecting its photophysical properties. Therefore, the ability to design a structure with atomic precision as described herein would lead to the fine-tuning of the electronic properties of insulated molecular wires.
