Check Digit Verification of cas no

The CAS Registry Mumber 4559-64-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,5 and 9 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4559-64:
(6*4)+(5*5)+(4*5)+(3*9)+(2*6)+(1*4)=112
112 % 10 = 2
So 4559-64-2 is a valid CAS Registry Number.

Visible-light-mediated synthesis of substituted phenazine and phenoxazinone using eosin y as a photoredox catalyst

Dhar, Basab Bijayi,Dhara, Ashish Kumar,Maity, Sayantan

supporting information, p. 3269 - 3273 (2021/05/31)

This paper describes an efficient, sustainable, one-step procedure for synthesizing substituted phenazines and phenoxazinones from commercially available ortho-substituted aromatic amines with very good yield (≥80%) in water. The procedure uses eosin Y (EY) as a photoredox catalyst at room temperature (RT). The highly reactive o-quinone-diimine or o-quinone-imine intermediate was characterized by the HR-MS technique.
