1228349-41-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1228349-41-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,3,4 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1228349-41:
(9*1)+(8*2)+(7*2)+(6*8)+(5*3)+(4*4)+(3*9)+(2*4)+(1*1)=154
154 % 10 = 4
So 1228349-41-4 is a valid CAS Registry Number.

New bis(15-crown-5) derivatives and their physicochemical properties
Kus, Piotr
experimental part, p. 58 - 64 (2010/09/07)
Two novel bis-crown ethers 1 and 2 were obtained. Both compounds form complexes with alkali metal ions. Such formation process was investigated using mass spectrometry (ESI MS). Compounds 1 and 2 can form both mono- and bimetallic complexes. Detected also
