Check Digit Verification of cas no

The CAS Registry Mumber 1261628-25-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,1,6,2 and 8 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1261628-25:
(9*1)+(8*2)+(7*6)+(6*1)+(5*6)+(4*2)+(3*8)+(2*2)+(1*5)=144
144 % 10 = 4
So 1261628-25-4 is a valid CAS Registry Number.

External-Photocatalyst-Free Visible-Light-Mediated Synthesis of Indolizines

Sahoo, Basudev,Hopkinson, Matthew N.,Glorius, Frank

, p. 15545 - 15549 (2015)

A visible-light-mediated synthesis of valuable polycyclic indolizine heterocycles from easily accessed brominated pyridine and enol carbamate derivatives has been developed. This process, which operates at room temperature under irradiation from readily available light sources, does not require the addition of an external photocatalyst. Instead, an investigation into the reaction mechanism indicates that the indolizine products themselves may be in some way involved in mediating and accelerating their own formation. Preliminary studies also show that these simple heterocyclic compounds may be capable of facilitating other visible-light-mediated transformations.
