Check Digit Verification of cas no
The CAS Registry Mumber 56316-86-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,3,1 and 6 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 56316-86:
(7*5)+(6*6)+(5*3)+(4*1)+(3*6)+(2*8)+(1*6)=130
130 % 10 = 0
So 56316-86-0 is a valid CAS Registry Number.

Pseudo five-component synthesis of 2,5-di(hetero)arylthiophenes via a one-pot Sonogashira-Glaser cyclization sequence
Urselmann, Dominik,Antovic, Dragutin,Mueller, Thomas J. J.
, p. 1499 - 1503 (2011/12/22)
Based upon a consecutive one-pot Sonogashira-Glaser coupling-cyclization sequence a variety of 2,5-di(hetero)arylthiophenes were synthesized in moderate to good yields. A single Pd/Cu-catalyst system, without further catalyst addition, and easily available, stable starting materials were used, resulting in a concise and highly efficient route for the synthesis of the title compounds. This novel pseudo five-component synthesis starting from iodo(hetero)arenes is particularly suitable as a direct access to well-defined thiophene oligomers, which are of peculiar interest in materials science.
Synthesis of thiophene/phenylene co-oligomers. II [1]. Block and alternating co-oligomers
Hotta,Kimura,Lee,Tamaki
, p. 281 - 286 (2007/10/03)
We report the synthesis of block and alternating thiophene/phenylene co- oligomers that is based either on the Suzuki coupling reaction or on the Grignard reaction. These reaction schemes enable us to obtain the target compounds at reasonably high yields.
