3333-23-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3333-23-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,3 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3333-23:
(6*3)+(5*3)+(4*3)+(3*3)+(2*2)+(1*3)=61
61 % 10 = 1
So 3333-23-1 is a valid CAS Registry Number.

Hydroxide ion as electron source for photochemical Birch-type reduction and photodehalogenation

The photochemical Birch-type reduction of arenes and the photodehalogenation of haloarenes by a hydroxide ion that acted as an electron source occurred in 2-PrOH. The efficiency of these photoreactions was dependent on the nature of the substrate, the concentration of NaOH, and the solvent used. These photoreactions provide an environmentally friendly method for the reduction of aromatic rings and dehalogenation.
