1201594-21-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1201594-21-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,1,5,9 and 4 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1201594-21:
(9*1)+(8*2)+(7*0)+(6*1)+(5*5)+(4*9)+(3*4)+(2*2)+(1*1)=109
109 % 10 = 9
So 1201594-21-9 is a valid CAS Registry Number.

Nickel-catalyzed amination of aryl sulfamates

Ramgren, Stephen D.,Silberstein, Amanda L.,Yang, Yang,Garg, Neil K.

, p. 2171 - 2173 (2011/04/25)

Broad in scope: The first amination of aryl sulfamates, which are attractive cross-coupling partners, particularly for multistep syntheses, was achieved by using a nickel catalyst. The method provides a versatile means to use simple derivatives of phenol as precursors to polysubstituted aryl amines, as exemplified by a concise synthesis of the antibacterial drug linezolid (see scheme).

Suzuki-Miyaura coupling of aryl carbamates, carbonates, and sulfamates

Quasdorf, Kyle W.,Riener, Michelle,Petrova, Krastina V.,Garg, Neil K.

supporting information; experimental part, p. 17748 - 17749 (2010/04/01)

(Chemical Equation Presented) The first Suzuki-Miyaura cross-couplings of carbamates, carbonates, and sulfamates is described. The method provides a powerful means of using simple derivatives of phenol as precursors to polysubstituted aromatic compounds, as exemplified by a concise synthesis of the anti-inflammatory drug flurbiprofen.
