222-75-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 222-75-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,2 and 2 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 222-75:
(5*2)+(4*2)+(3*2)+(2*7)+(1*5)=43
43 % 10 = 3
So 222-75-3 is a valid CAS Registry Number.

Synthesis of Polycyclic Aromatic Hydrocarbons (PAHs) via a Transient Directing Group

Tang, Ming,Yu, Qinqin,Wang, Ziqi,Zhang, Chen,Sun, Bing,Yi, Ying,Zhang, Fang-Lin

supporting information, p. 7620 - 7623 (2018/12/11)

In this work, an efficient synthetic route was developed to construct PAHs with diverse shape, width, and edge topology. The precursors of PAHs were obtained by using a direct arylation of arenes via a transient ligand-directed C-H functionalization strategy and the cycloaromatization was readily achieved by using a Br?nsted acid catalyst. This novel route provides an opportunity to build up PAHs in a highly efficient manner.
