191-13-9 Usage
Uses
Used in Organic Synthesis Industry:
Pyranthrene is used as a precursor for the synthesis of various organic materials, contributing to the development of new compounds and products in the chemical industry.
Due to the hazardous nature of Pyranthrene, its applications are limited, and strict regulations are in place to minimize its environmental and health impacts.
Check Digit Verification of cas no
The CAS Registry Mumber 191-13-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,9 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 191-13:
(5*1)+(4*9)+(3*1)+(2*1)+(1*3)=49
49 % 10 = 9
So 191-13-9 is a valid CAS Registry Number.

Modular Approach to the Synthesis of Two-Dimensional Angular Fused Acenes
Feofanov, Mikhail,Akhmetov, Vladimir,Sharapa, Dmitry I.,Amsharov, Konstantin
, p. 1698 - 1702 (2020/01/31)
Herein, we present a modular approach to pristine angularly fused planar acenes. The approach includes the Pd-catalyzed fusion of several building blocks and implements a dehydrative ?-extension (DPEX) reaction as a key step enabling facile access to diverse two-dimensional acenes. The scope was demonstrated on nine examples with up to quantitative yield.
