Check Digit Verification of cas no

The CAS Registry Mumber 1202398-95-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,2,3,9 and 8 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1202398-95:
(9*1)+(8*2)+(7*0)+(6*2)+(5*3)+(4*9)+(3*8)+(2*9)+(1*5)=135
135 % 10 = 5
So 1202398-95-5 is a valid CAS Registry Number.

Heterogenized Cu (II) salen complex grafted on graphene oxide nanosheets as a precursing catalyst for the Pd-free Sonogashira coupling

Ghabdian, Mahdieh,Nasseri, Mohammad A.,Allahresani, Ali,Motavallizadehkakhky, Alireza

, (2018)

Cu (II) salen complex immobilized on graphene oxide nanosheets [Cu (II) salen@GO] was synthesized with 3-chloropropyltrimethoxysilan as a linker and wholly characterized using various techniques like X-ray diffraction, Fourier-transform infrared, scanning electron microscopy/energy-dispersive X-ray spectroscopy, transmission electron microscopy, as well as atomic absorption spectroscopy (AAS). Cu (II) salen@GO as an effective heterogeneous catalyst has been investigated for the Sonogashira coupling reaction in dimethylsulfoxide with good to high yield (98%) in 4?hr at 110°C when the loading of Cu was 0.7?mmol?g?1 based on Cu element analysis by AAS. It was understood that heterogeneous catalyst was as active as its homogeneous analog, and presented good recoverability and no significant loss in activity within successive runs.
