221-11-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 221-11-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,2 and 1 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 221-11:
(5*2)+(4*2)+(3*1)+(2*1)+(1*1)=24
24 % 10 = 4
So 221-11-4 is a valid CAS Registry Number.

Cascade annulative π-extension for the rapid construction of carbazole based polyaromatic hydrocarbons

Banerjee, Ankush,Ghosh, Meghna,Kundu, Samrat,Maji, Modhu Sudan,Pal, Shyam Chand

supporting information, p. 5762 - 5765 (2021/06/16)

A Br?nsted acid catalyzed cascade benzannulation strategy for the one-pot synthesis of densely populated poly-aryl benzo[a]carbazole architectures is disclosed from easily affordable fundamental commodities. The efficacy of this technique was further validated via the concise synthesis of structurally unique carbazole based poly-aromatic hydrocarbons. Furthermore, the photo-physical properties of the synthesized compounds are thoroughly investigated.
