Check Digit Verification of cas no

The CAS Registry Mumber 1428766-99-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,7,6 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1428766-99:
(9*1)+(8*4)+(7*2)+(6*8)+(5*7)+(4*6)+(3*6)+(2*9)+(1*9)=207
207 % 10 = 7
So 1428766-99-7 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

, p. 1955 - 1964 (2013)

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.
