161259-72-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 161259-72-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,2,5 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 161259-72:
(8*1)+(7*6)+(6*1)+(5*2)+(4*5)+(3*9)+(2*7)+(1*2)=129
129 % 10 = 9
So 161259-72-9 is a valid CAS Registry Number.

Tris(polymethoxyphenyl)bismuth derivatives: Synthesis and reactivity
Finet, Jean-Pierre,Fedorov, Alexey Yu.
, p. 2386 - 2393 (2007/10/03)
Tris-(polymethoxyphenyl)bismuth diacetate and dichloride derivatives react with C-nucleophiles in basic medium, as well as with N- and O-nucleophiles under copper catalysis to give good to high yields of the corresponding C-, N- and O-arylation products.
