Check Digit Verification of cas no

The CAS Registry Mumber 1438436-03-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,8,4,3 and 6 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1438436-03:
(9*1)+(8*4)+(7*3)+(6*8)+(5*4)+(4*3)+(3*6)+(2*0)+(1*3)=163
163 % 10 = 3
So 1438436-03-3 is a valid CAS Registry Number.

Visible-Light-Induced Metal-/Photocatalyst-Free C-H Bond Imidation of Arenes

Kuribara, Takahito,Nakajima, Masaya,Nemoto, Tetsuhiro

supporting information, p. 2235 - 2239 (2020/03/13)

In this study, a visible-light-induced intermolecular C-H bond imidation of arenes was achieved at ambient condition. By using simple phthalimide with (diacetoxyiodo)benzene and molecular iodine, direct metal-/photocatalyst-free C-N bond formation was achieved. The imidation protocol was designed by using time-dependent density functional theory calculations and experimentally demonstrated for 28 substrates with as high as 96% yield. Mechanistic studies indicated that radical-mediated aromatic substitution occurred via photolysis of N-iodophthalimide under visible-light irradiation.
