Check Digit Verification of cas no

The CAS Registry Mumber 1338469-65-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,4,6 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1338469-65:
(9*1)+(8*3)+(7*3)+(6*8)+(5*4)+(4*6)+(3*9)+(2*6)+(1*5)=190
190 % 10 = 0
So 1338469-65-0 is a valid CAS Registry Number.

Synthesis of Imidazo[1,2- a]pyridines via Near UV Light-Induced Cyclization of Azirinylpyridinium Salts

Agafonova, Anastasiya V.,Filippov, Ilya P.,Khlebnikov, Alexander F.,Novikov, Mikhail S.,Rostovskii, Nikolai V.,Smetanin, Ilia A.,Titov, Gleb D.

supporting information, p. 6514 - 6519 (2022/05/04)

An efficient one-pot synthesis of imidazo[1,2-a]pyridines from 2-bromoazirines and pyridines has been developed. The construction of the bicyclic framework of imidazo[1,2-a]pyridines occurs in two steps through the formation of (2H-azirin-2-yl)pyridinium bromides followed by dehydrobrominative UV light-induced cyclization. The method can also be applied for the synthesis of imidazo[2,1-a]isoquinolines. Unstable in solution, (2H-azirin-2-yl)pyridinium/isoquinolinium bromides were quantitatively converted to stable tetrafluoroborates, which can be cyclized to imidazo[1,2-a]pyridines under UV irradiation in the presence of bromide ions.

Cu(I)-catalysed oxidative coupling of 2-aminopyridines with β-keto esters: Synthesis of imidazo[1,2-a]pyridine-3-carboxylates

Li, Xiaoqing

, p. 525 - 527 (2012/10/30)

A simple, economical, and environmentally friendly copper-catalysed direct oxidative C-N coupling of 2-aminopyridines with β-keto esters using air as oxidation agent for the creation of imidazo[1,2-a]pyridine-3-carboxylates is demonstrated. Imidazo[1,2-a]pyridine is the basic skeleton for a wide range of biological and pharmacological compounds.

Synthesis of imidazo[1,2-a]pyridines by the bis(acetyloxy)(phenyl)- λ3-iodane-Mediated oxidative coupling of 2-aminopyridines with β-keto esters and 1,3-diones

Wang, Xianpei,Ma, Lijuan,Yu, Wei

supporting information; experimental part, p. 2445 - 2453 (2011/09/15)

Imidazo[1,2-a]pyridine-3-carboxylates can be prepared directly from 2-aminopyridines and β-keto esters by using bis(acetyloxy)(phenyl)- λ3-iodane as an oxidant and boron trifluoride etherate as a catalyst. The amount of catalyst plays a key rol

TBAI-catalyzed oxidative coupling of aminopyridines with β-keto esters and 1,3-diones - Synthesis of imidazo[1,2-a]pyridines

Ma, Lijuan,Wang, Xianpei,Yu, Wei,Han, Bing

supporting information; experimental part, p. 11333 - 11335 (2011/11/29)

TBAI could catalyze the direct oxidative C-N coupling of 2-aminopyridines with β-keto esters and 1,3-diones, which affords imidazo[1,2-a]pyridines as the products. The reaction was realized under metal-free conditions by using tert-butyl hydroperoxide (TB
