19920-85-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 19920-85-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,2 and 0 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 19920-85:
(7*1)+(6*9)+(5*9)+(4*2)+(3*0)+(2*8)+(1*5)=135
135 % 10 = 5
So 19920-85-5 is a valid CAS Registry Number.

Generation of bromophenyllithium reagents from dibromobenzenes and addition to carbonyl and nitrile electrophiles

Caron, Stéphane,Do, Nga M.

, p. 1440 - 1442 (2004)

An evaluation of the mono-lithiation of all three regioisomers of dibromobenzene using n-butylithium was performed. The resulting aryllithium reagents were added to electrophiles such as ketones, aldehydes, nitriles and amides to afford the desired benzylic alcohols or ketones.

Diethylaminosulfur trifluoride-mediated intramolecular cyclization of 2-hydroxycycloalkylureas to fused bicyclic aminooxazoline compounds and evaluation of their biochemical activity against β-secretase-1 (BACE-1)

Huestis, Malcolm P.,Liu, Wendy,Volgraf, Matthew,Purkey, Hans E.,Yu, Christine,Wang, Weiru,Smith, Darin,Vigers, Guy,Dutcher, Darrin,Hunt, Kevin W.,Siu, Michael

, p. 5802 - 5807 (2013/10/01)

A series of unique bicyclic aminooxazolines were synthesized and found to exhibit micromolar inhibition of β-secretase-1 (BACE-1). The aminooxazolines were procured by an intramolecular diethylaminosulfur trifluoride (DAST)-mediated ring closure of a benz

Potent and selective cathepsin K inhibitors

, p. 6789 - 6806 (2007/10/03)

A novel series of cathepsin K inhibitors derived from Novartis compound I is described. Optimization of the P1, P3, and P1′ units led to the identification of 4-aminophenoxyacetic acid 24b with an IC50 value of 4.8 nM, which possessed an excell
