939881-09-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 939881-09-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,9,8,8 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 939881-09:
(8*9)+(7*3)+(6*9)+(5*8)+(4*8)+(3*1)+(2*0)+(1*9)=231
231 % 10 = 1
So 939881-09-1 is a valid CAS Registry Number.

Synthesis and polymerisation of α,ω-bis(3-pyrrolyl)alkanes
Foitzik, Richard C.,Kaynak, Akif,Pfeffer, Frederick M.
, p. 4237 - 4242 (2007/10/03)
The synthesis, characterisation and polymerisation studies of a homologous series of α,ω-bis(pyrrolyl)alkanes are described. These α,ω-bis(pyrrolyl)alkanes were produced using Friedel-Crafts acylation followed by reduction of the carbonyl group using Red-
