1219825-55-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1219825-55-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,9,8,2 and 5 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1219825-55:
(9*1)+(8*2)+(7*1)+(6*9)+(5*8)+(4*2)+(3*5)+(2*5)+(1*5)=164
164 % 10 = 4
So 1219825-55-4 is a valid CAS Registry Number.

Zirconacyclopentadiene-Annulated Polycyclic Aromatic Hydrocarbons
Kiel, Gavin R.,Ziegler, Micah S.,Tilley, T. Don
supporting information, p. 4839 - 4844 (2017/04/11)
Syntheses of large polycyclic aromatic hydrocarbons (PAHs) and graphene nanostructures demand methods that are capable of selectively and efficiently fusing large numbers of aromatic rings, yet such methods remain scarce. Herein, we report a new approach
