202-72-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 202-72-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,0 and 2 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 202-72:
(5*2)+(4*0)+(3*2)+(2*7)+(1*2)=32
32 % 10 = 2
So 202-72-2 is a valid CAS Registry Number.

Steering Scholl Oxidative Heterocoupling by Tuning Topology and Electronics for Building Thiananographenes and Their Functional N?/C?Congeners

Maddala, Sudhakar,Panua, Anirban,Venkatakrishnan, Parthasarathy

supporting information, p. 16013 - 16020 (2021/10/08)

While intramolecular Scholl oxidative coupling between two arenes is common, successful C?C heterocoupling between thiophene and arene is scarce. The latter is due to the notorious reactivity of thiophene towards polymerization under oxidative conditions.

Accessing π-expanded heterocyclics beyond dibenzothiophene: Syntheses and properties of phenanthrothiophenes

Venkateswarlu, Samala,Prakoso, Suhendro Purbo,Kumar, Sushil,Tao, Yu-Tai

, p. 437 - 445 (2020/02/13)

A series of phenanthrothiophenes are designed and synthesized from polyarylthiophenes through regioselective Scholl reactions in one step using iron chloride as catalyst. The molecular structures of these heteroarenes displayed multiple twisted fjords, which perturb the shapes of the polycyclic frameworks to pack in slipped to near-perfect face-to-face styles in parallel or antiparallel packings. Field-effect transistor devices using single crystals of 6,12-difluorodiphenanthro[9, 10-b:9′, 10′]thiophene gave a hole mobility of 0.22 cm2 V?1 s?1.
