23238-41-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 23238-41-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,2,3 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 23238-41:
(7*2)+(6*3)+(5*2)+(4*3)+(3*8)+(2*4)+(1*1)=87
87 % 10 = 7
So 23238-41-7 is a valid CAS Registry Number.

Phase-Transfer Synthesis of Monoalkyl Ethers of Oligoethylene Glycols
Gibson, Thomas
, p. 1095 - 1098 (2007/10/02)
The effects of catalyst, temperature, solvent, and reagent ratios on the phase-transfer-catalyzed Williamson ether synthesis of monoalkyl ethers of oligoethylene glycols have been studied.A convenient method has been developed which gives reproducibly high yields of pure monoethers in the presence of aqueous sodium hydroxide.
