Check Digit Verification of cas no
The CAS Registry Mumber 139101-23-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,1,0 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 139101-23:
(8*1)+(7*3)+(6*9)+(5*1)+(4*0)+(3*1)+(2*2)+(1*3)=98
98 % 10 = 8
So 139101-23-8 is a valid CAS Registry Number.

A novel photoredox-catalyzed radical addition of methylene-2-oxazolines has been developed under visible light irradiation to synthesize monofluorooxazoles with a quaternary carbon center using 2-bromo-2-fluoro-3-oxo-3-phenylpropionates as radical source. This method with a simple protocol, scalability and high yield offers a facile path to get diverse monofluorinated oxazoles with quaternary C-F centers, which are a class of highly valuable motifs and synthons.
