Check Digit Verification of cas no
The CAS Registry Mumber 16672-78-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,6,7 and 2 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 16672-78:
(7*1)+(6*6)+(5*6)+(4*7)+(3*2)+(2*7)+(1*8)=129
129 % 10 = 9
So 16672-78-9 is a valid CAS Registry Number.

Palladium-Catalyzed Phase-Transfer Arylation of Dialkyl Phosphonates
Kabachnik,Solntseva,Izmer,Novikova,Beletskaya
, p. 93 - 97 (2007/10/03)
Palladium-catalyzed phase-transfer arylation of dialkyl phosphonates with various iodo- and bromoarenes has been studied. The arylation has also been effected in the absence of ligand. A simple preparative procedure for synthesizing arylphosphonic acids has been developed.
