Check Digit Verification of cas no
The CAS Registry Mumber 721969-93-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,1,9,6 and 9 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 721969-93:
(8*7)+(7*2)+(6*1)+(5*9)+(4*6)+(3*9)+(2*9)+(1*3)=193
193 % 10 = 3
So 721969-93-3 is a valid CAS Registry Number.

Regioselective Synthesis of 2- or 2,7-Functionalized Pyrenes via Migration

A simple method for the preparation of 2- or 2,7-functional pyrenes from 1- or 1,6-substituted derivatives is reported. The synthesis involves the unexpected 1,2-phosphinyl migration in an AlCl3/NaCl melt. The structure of the product has been unambiguously confirmed by X-ray crystallography. We also demonstrated that further functionalization of pyrene through C-P bond activation is possible. These 2,7-positions are difficult to derivatize otherwise.
