188720-10-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 188720-10-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,7,2 and 0 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 188720-10:
(8*1)+(7*8)+(6*8)+(5*7)+(4*2)+(3*0)+(2*1)+(1*0)=157
157 % 10 = 7
So 188720-10-7 is a valid CAS Registry Number.

Alkyne Cycloadditions Mediated by Tetrabutylammonium Fluoride: A Unified and Diversifiable Route to Isoxazolines and Pyrazolines

Nagy, Edith,Lepore, Salvatore D.

supporting information, p. 3695 - 3698 (2017/07/26)

A versatile approach to isoxazolines and pyrazolines by the cyclization of alkyne substrates using tetrabutylammonium fluoride (TBAF) is described. The reported diheteroatom cycles were produced under mild reaction conditions and with broad product scope.

Design and synthesis of m1-selective muscarinic agonists: (R)-(-)-(Z)- 1-azabicyclo[2.2.1]heptan-3-one, O-(3-(3'-methoxyphenyl)-2-propynyl)-oxime maleate (CI-1017), a functionally m1-selective muscarinic agonist

, p. 2524 - 2536 (2007/10/03)

The synthesis and SAR of a series of (Z)-(±)-1- azabicyclo[2.2.1]heptan-3-one, O-(3-aryl-2-propynyl)oximes are described. The biochemistry and pharmacology of 24Z (PD 142505) and its enantiomers are highlighted. 24Z is functionally an m1-selective muscari
