81979-64-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81979-64-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,9,7 and 9 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 81979-64:
(7*8)+(6*1)+(5*9)+(4*7)+(3*9)+(2*6)+(1*4)=178
178 % 10 = 8
So 81979-64-8 is a valid CAS Registry Number.

The use of rhodium catalysts such as [RhCl(PPh3)3] or [{RhCl(COD)}2] with PiPr2(OAr) or P(NMe 2)3 co-catalysts allows the ortho-selective intermolecular arylation of phenols. The reaction p
