Check Digit Verification of cas no

The CAS Registry Mumber 1316844-18-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,6,8,4 and 4 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1316844-18:
(9*1)+(8*3)+(7*1)+(6*6)+(5*8)+(4*4)+(3*4)+(2*1)+(1*8)=154
154 % 10 = 4
So 1316844-18-4 is a valid CAS Registry Number.

Iodonium salts are key intermediates in Pd-catalyzed acetoxylation of pyrroles

Lubriks, Dmitrijs,Sokolovs, Igors,Suna, Edgars

scheme or table, p. 4324 - 4327 (2011/10/05)

A mild, room-temperature Pd-catalyzed acetoxylation of pyrroles with phenyliodonium acetate is described. The acetoxylation was found to proceed via the initial formation of pyrrolyl(phenyl)iodonium acetates, which were converted to acetoxypyrroles in the presence of Pd(OAc)2. The acetoxylation could also be carried out as a one-pot sequential procedure without the isolation of the intermediate iodonium salts.
