Check Digit Verification of cas no

The CAS Registry Mumber 1335008-75-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,5,0,0 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1335008-75:
(9*1)+(8*3)+(7*3)+(6*5)+(5*0)+(4*0)+(3*8)+(2*7)+(1*5)=127
127 % 10 = 7
So 1335008-75-7 is a valid CAS Registry Number.

Site-Specific Oxidative C-H Chalcogenation of (Hetero)Aryl-Fused Cyclic Amines Enabled by Nanocobalt Oxides

Tan, Zhenda,Liang, Yantang,Yang, Jian,Cao, Liang,Jiang, Huanfeng,Zhang, Min

supporting information, p. 6554 - 6558 (2018/10/20)

By employing reusable nanocobalt oxides as the catalysts, a site-specific oxidative C-H chalcogenation of (hetero)aryl-fused cyclic amines with various thiols and diselenides is presented for the first time. The reaction proceeds selectively at the sites of the (hetero)aryl rings para to the N atom, and enables access to a wide array of chalcogenyl N-heteroarenes. The merits of the transformation involve high step- and atom-efficiency, excellent substrate and functional compatibility, operational simplicity, and the use of a naturally abundant Co/O2 system. The present work has offered a fundamental basis for the selective synthesis of functional N-heteroarenes from readily available feedstocks.
