Check Digit Verification of cas no

The CAS Registry Mumber 264600-78-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,4,6,0 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 264600-78:
(8*2)+(7*6)+(6*4)+(5*6)+(4*0)+(3*0)+(2*7)+(1*8)=134
134 % 10 = 4
So 264600-78-4 is a valid CAS Registry Number.

Synthesis of 3-Aminoimidazo[1,2-a]pyridines from α-Aminopyridinyl Amides

Régnier, Sophie,Bechara, William S.,Charette, André B.

, p. 10348 - 10356 (2016)

3-Aminoimidazo[1,2-a]pyridines are rapidly synthesized via a facile and mild cyclodehydration-aromatization reaction starting from readily available amides. The cyclodehydration step is mediated by the activation of N-Boc-protected 2-aminopyridine-containing amides by triflic anhydride (Tf2O) in the presence of 2-methoxypyridine (2-MeO-Py). Subsequently, the addition of K2CO3 in THF ensured a clean deprotection-aromatization sequence to afford the desired heterocycle. A wide variety of functional groups and substitution patterns were tolerated under the optimized procedure, and good to excellent yields were obtained for the fused bicyclic 3-aza-heterocycles. In addition, the reaction was found to be scalable to gram-scale and could be performed with unprotected acyclic amide precursors. We also found that the resulting products were valuable intermediates for both Pd- and Ru-catalyzed C-H arylation reactions, allowing for the elaboration to diversely functionalized building blocks.
