1101-42-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1101-42-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,0 and 1 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1101-42:
(6*1)+(5*1)+(4*0)+(3*1)+(2*4)+(1*2)=24
24 % 10 = 4
So 1101-42-4 is a valid CAS Registry Number.

Copper-catalyzed C-N cross-coupling of substituted 2-halobenzoates with secondary acyclic amides

Wang, Man-Gang,Yu, Hua,Wu, Jun,Shang, Zhi-Cai

supporting information, p. 1955 - 1964 (2013/07/26)

The copper-catalyzed C-N cross-coupling of poorly nucleophilic acyclic secondary amides with sterically hindered substituted 2-halobenzoates has been demonstrated with 1,4-dimethyl-3,4-dihydro-1H-benzo[e][1,4]diazepin-5(2H)-one (DMBDO) as ligands for the first time. The protocol is effective for the synthesis of hindered tertiary amides. We also found that the alkoxycarbonyl (CO2R) group has a strong ortho-substituent effect on a Goldberg-type C-N coupling reaction. Georg Thieme Verlag Stuttgart. New York.
