63867-25-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 63867-25-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,8,6 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 63867-25:
(7*6)+(6*3)+(5*8)+(4*6)+(3*7)+(2*2)+(1*5)=154
154 % 10 = 4
So 63867-25-4 is a valid CAS Registry Number.

, p. 6754 - 6765 (2015/06/25)
The requirement of aryl ring activation by strong-electron withdrawing substituents in substrates for the intramolecular nucleophilic aromatic substitution reaction known as the Truce-Smiles rearrangement was examined. Preliminary mechanistic experiments
