Check Digit Verification of cas no

The CAS Registry Mumber 1609401-43-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,9,4,0 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1609401-43:
(9*1)+(8*6)+(7*0)+(6*9)+(5*4)+(4*0)+(3*1)+(2*4)+(1*3)=145
145 % 10 = 5
So 1609401-43-5 is a valid CAS Registry Number.

Nickel-Catalyzed Ortho C–H Methylation of Aromatic Amides with Di-tert-butyl Peroxide as Methylation Reagent

Liu, Da,Yu, Lin,Yu, Yongqi,Xia, Zhen,Song, Zenan,Liao, Lihong,Tan, Ze,Chen, Xiang

supporting information, p. 6930 - 6934 (2019/11/13)

A new efficient protocol for the ortho-methylation of benzamides with DTBP has been developed via Ni(II)-catalyzed C–H activation directed by 8-aminoquinoline. This method is performed under base-free, ligand-free conditions and utilizes cheap and commercially available reagents. Moreover, the by-product acetone derived from DTBP does not affect the purification of the product.

Isoindolone synthesis via palladium-catalysed intramolecular amination of benzylic C-H bonds

Zhang, Ming

, p. 606 - 610 (2013/11/06)

A new method for the construction of isoindolones is presented in this paper. Four 7-methyl-2-(8-quinolinyl)-2,3-dihydro-1Hisoindol-1-ones were synthesised from 2,6-dimethyl -N-(8-quinolinyl)benzamides via intramolecular direct amination of benzylic C-H bonds. This approach provides a convenient method affording structurally new isoindolones for medicinal chemistry research.
