Check Digit Verification of cas no

The CAS Registry Mumber 89192-94-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,1,9 and 2 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 89192-94:
(7*8)+(6*9)+(5*1)+(4*9)+(3*2)+(2*9)+(1*4)=179
179 % 10 = 9
So 89192-94-9 is a valid CAS Registry Number.

I2-mediated and direct synthesis of 3-phenoxy imidazo heterocycles

Guo, Yanchun,Wang, Yuexiu,Xue, Han,Cao, Shuxia,Zhao, Yufen

, p. 1481 - 1491 (2019)

An I2-mediated protocol was proposed for the synthesis of 3-phenoxy imidazo heterocycles from aromatic ketones and 2-aminopyridines or 2-aminobenzothiazole. This direct, efficient and operationally simple method provided a fundamentally novel a

Visible Light Organic Photoredox-Catalyzed C-H Alkoxylation of Imidazopyridine with Alcohol

Kibriya, Golam,Samanta, Sadhanendu,Jana, Sourav,Mondal, Susmita,Hajra, Alakananda

, p. 13722 - 13727 (2017)

The visible light-mediated C-3 alkoxylation of imidazopyridines with alcohols has been achieved using rose bengal as an organic photoredox catalyst at room temperature. Widely abundant air acts as the terminal oxidant that avoids the use of a stoichiometric amount of peroxo compounds. A wide range of functional groups could be tolerated under the reaction conditions to produce C(sp2)-H alkoxylated products in high yields.
