Check Digit Verification of cas no

The CAS Registry Mumber 1401518-67-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,1,5,1 and 8 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1401518-67:
(9*1)+(8*4)+(7*0)+(6*1)+(5*5)+(4*1)+(3*8)+(2*6)+(1*7)=119
119 % 10 = 9
So 1401518-67-9 is a valid CAS Registry Number.

Nickel-Catalyzed C(sp2)-H/C(sp3)-H Oxidative Coupling of Indoles with Toluene Derivatives

Soni, Vineeta,Khake, Shrikant M.,Punji, Benudhar

, p. 4202 - 4208 (2017/06/19)

Nickel-catalyzed oxidative C(sp2)-H/C(sp3)-H coupling of indoles with toluene derivatives is successfully achieved in the presence of 2-iodobutane as the oxidant. This method allows the selective C-2 benzylation of indoles with toluene derivatives over the alkylation with 2-iodobutane and permits the coupling of diversified indoles via the monochelation assistance. The reaction proceeded through a single-electron-transfer (SET) process, wherein both the C-H nickelation of indole and the C-H activation of toluene derivatives have a significant effect on the entire reaction rate. The synthetic utility of this nickel-catalyzed protocol is demonstrated by the facile removal of the directing group and by the convenient synthesis of the melatonin receptor antagonist Luzindole derivatives.

Cobalt-catalyzed direct arylation and benzylation by C-H/C-O cleavage with sulfamates, carbamates, and phosphates

Song, Weifeng,Ackermann, Lutz

supporting information; experimental part, p. 8251 - 8254 (2012/09/07)

Inexpensive cobalt catalysts enable the first direct arylation and benzylation of (hetero)arenes with aryl carbamates, sulfamates, and phosphates with ample scope. The non-radical C-H/C-O arylation reaction even proved viable at ambient temperature. Copyr
