1268444-44-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1268444-44-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,8,4,4 and 4 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1268444-44:
(9*1)+(8*2)+(7*6)+(6*8)+(5*4)+(4*4)+(3*4)+(2*4)+(1*4)=175
175 % 10 = 5
So 1268444-44-5 is a valid CAS Registry Number.

Synthesis of nitroaryl derivatives of glycine via oxidative nucleophilic substitution of hydrogen in nitroarenes

Ma?kosza, Mieczys?aw,Chromi?ski, Miko?aj,Sulikowski, Daniel

experimental part, p. 82 - 91 (2011/06/20)

Carbanion of ethyl N-(1,3-dithiolan-2-ylidene)glycinate adds to activated nitroarenes mostly in para position to the nitro group. Subsequent oxidation of the resulting σH adducts with DDQ gave respective α-nitroarylated glycine derivatives in moderate yields. The reaction of esters of chiral alcohols such as (-)-menthol or (-)-8-phenylmenthol proceeds with a moderate or high diastereoselectivity leading to enantiomerically enriched nitroarylglycines.
