1290634-39-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1290634-39-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,0,6,3 and 4 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1290634-39:
(9*1)+(8*2)+(7*9)+(6*0)+(5*6)+(4*3)+(3*4)+(2*3)+(1*9)=157
157 % 10 = 7
So 1290634-39-7 is a valid CAS Registry Number.

Manganese-catalyzed directed methylation of C(sp2)-H bonds at 25 °C with high catalytic turnover

Sato, Takenari,Yoshida, Takumi,Al Mamari, Hamad H.,Ilies, Laurean,Nakamura, Eiichi

supporting information, p. 5458 - 5461 (2017/11/06)

We report here a manganese-catalyzed C-H methylation reaction of considerable substrate scope, using MeMgBr, a catalytic amount of MnCl2· 2LiCl, and an organic dihalide oxidant. The reaction features ambient temperature, low catalyst loading, typically 1%, high catalytic turnover reaching 5.9 × 103, and no need for an extraneous ligand and illustrates a unique catalytic use of simple manganese salts for C-H activation, which so far has relied on catalysis by manganese carbonyls.
