Check Digit Verification of cas no
The CAS Registry Mumber 77557-03-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,5,5 and 7 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77557-03:
(7*7)+(6*7)+(5*5)+(4*5)+(3*7)+(2*0)+(1*3)=160
160 % 10 = 0
So 77557-03-0 is a valid CAS Registry Number.

Photocatalytic Intramolecular C-H Amination Using N-Oxyureas as Nitrene Precursors

Nitrenes are remarkable high-energy chemical species that enable direct C-N bond formation, typically via controlled reactions of metal-stabilized nitrenes. Here, in contrast, the combined use of photocatalysis with careful engineering of the precursor enabled C-H amination forming imidazolidinones and related nitrogen heterocycles from readily accessible hydroxylamine precursors. Preliminary mechanistic results are consistent with the formation of free carbamoyl triplet nitrenes as reactive intermediates.
