453-78-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 453-78-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,5 and 3 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 453-78:
(5*4)+(4*5)+(3*3)+(2*7)+(1*8)=71
71 % 10 = 1
So 453-78-1 is a valid CAS Registry Number.

Iron-catalysed radical cyclization to synthesize germanium-substituted indolo[2,1-a]isoquinolin-6(5H)-ones and indolin-2-ones

Li, Zhiping,Luo, Yani,Lv, Leiyang,Nishihara, Yasushi,Tian, Tian

supporting information, p. 9276 - 9279 (2021/09/20)

A simple and efficient strategy for iron-catalysed cascade radical cyclization was developed, by which an array of germanium-substituted indolo[2,1-a]isoquinolin-6(5H)-ones and indolin-2-ones were obtained in one pot with germanium hydrides as radical precursors. A rapid intramolecular radical trapping mode enabled the selective arylgermylation of alkenes over the prevalent hydrogermylation reaction.
