Check Digit Verification of cas no

The CAS Registry Mumber 24017-91-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,0,1 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 24017-91:
(7*2)+(6*4)+(5*0)+(4*1)+(3*7)+(2*9)+(1*1)=82
82 % 10 = 2
So 24017-91-2 is a valid CAS Registry Number.

Cobalt-Catalyzed Aerobic Oxidative C-H/C-H Cross-Coupling of Unactivated Arenes for the Synthesis of Biaryls

Lv, Ningning,Chen, Zhengkai,Liu, Yue,Liu, Zhanxiang,Zhang, Yuhong

, p. 5845 - 5848 (2018)

A mild and efficient protocol for the synthesis of 2,2′-difunctional biaryls from readily available benzamides and oximes by Co(OAc)2·4H2O catalysis has been developed. The catalytic cycle that includes aerobic oxidation of Co(I) to Co(III) is successfully achieved for the first time through dual-chelation-assisted C-H/C-H coupling with the assistance of catalytic Mn(acac)3. The catalytic system exhibits powerful reactivity and tolerates a large number of sensitive functional groups.

Copper-Catalyzed Formation of α-Alkoxycycloalkenones from N-Tosylhydrazones

Su, Naijing,Theorell, Juliana A.,Wink, Donald J.,Driver, Tom G.

supporting information, p. 12942 - 12946 (2015/11/02)

The combination of 20 mol % of copper iodide and lithium tert-butoxide triggers the formation of a broad range of substituted, functionalized α-alkoxy 2H-naphthalenones from readily available N-tosylhydrazones. The data suggests that this transformation occurs through cycloaddition of a copper carbenoid with an ester, followed by a Lewis acid-catalyzed [1,2] alkyl shift of the in situ generated alkoxyepoxide intermediate.
