1234031-34-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1234031-34-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,4,0,3 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1234031-34:
(9*1)+(8*2)+(7*3)+(6*4)+(5*0)+(4*3)+(3*1)+(2*3)+(1*4)=95
95 % 10 = 5
So 1234031-34-5 is a valid CAS Registry Number.

Synthesis of π-Conjugated polymers containing organoboron benzo[ h ]quinolate in the main chain
Tokoro, Yuichiro,Nagai, Atsushi,Chujo, Yoshiki
, p. 6229 - 6233 (2010)
A study was conducted to synthesize π-conjugated polymers containing organoboron benzo[h]quinolate in the main chain. cTetrahydrofuran (THF) and triethylamine (Et3N) were purified using a two-column solid-state purification system. 10-Hydroxybe
