1277175-10-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1277175-10-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,7,1,7 and 5 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1277175-10:
(9*1)+(8*2)+(7*7)+(6*7)+(5*1)+(4*7)+(3*5)+(2*1)+(1*0)=166
166 % 10 = 6
So 1277175-10-6 is a valid CAS Registry Number.

N-Phenoxyamides as Multitasking Reagents: Base-Controlled Selective Construction of Benzofurans or Dihydrobenzofuro[2,3- d]oxazoles

Li, Ming,Wang, Jia-Hui,Li, Wei,Lin, Cheng-Dong,Zhang, Lin-Bao,Wen, Li-Rong

, p. 8523 - 8530 (2019)

An efficient method to selectively construct benzofuran and dihydrobenzofuro[2,3-d]oxazole derivatives has been successfully established by means of base-controlled cyclization of N-phenoxyamides with 1-[(triisopropylsilyl)ethynyl]-1,2-benziodoxol-3(1H)-one (TIPS-EBX). N-phenoxyamides as multitasking reagents have triggered two different cascade reaction sequences. This is the first example of using TIPS-EBX for the transformation of C(sp) to either C(sp2) or C(sp3) under metal-free conditions.
