Check Digit Verification of cas no

The CAS Registry Mumber 861640-77-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,1,6,4 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 861640-77:
(8*8)+(7*6)+(6*1)+(5*6)+(4*4)+(3*0)+(2*7)+(1*7)=179
179 % 10 = 9
So 861640-77-9 is a valid CAS Registry Number.

Selective double functionalization of meso-tetraphenylporphyrin complexes on the same pyrrole unit by tandem electrophilic/nucleophilic aromatic substitution

Ostrowski, Stanislaw,Raczko, Anna M.

, p. 974 - 978 (2005)

The mono-nitrated meso-tetraphenylporphyrin (TPP) complex 2 could be readily functionalized on the substituted pyrrole ring with yields of up to 83%. These transformations were achieved via aromatic substitution with carbanions generated from diverse func
