4353-28-0 Usage
Safety Profile
Mildly toxic by ingestion and skin contact. Many glycol ethers have dangerous reproductive effects. When heated to decomposition it emits acrid smoke and irritating fumes.
Check Digit Verification of cas no
The CAS Registry Mumber 4353-28-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,5 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4353-28:
(6*4)+(5*3)+(4*5)+(3*3)+(2*2)+(1*8)=80
80 % 10 = 0
So 4353-28-0 is a valid CAS Registry Number.

SYNTHESIS OF DIALKYL ETHERS OF POLYETHYLENE GLYCOLS
Barnakov, Ch. N.,Volgin, A. A.
, p. 152 - 155 (2007/10/02)
Methods were developed for synthesis of dimethyl and diethyl ethers of polyethylene glycols in one step (without isolation of intermediates) with the general formula R(OC2H4)mOR, where R=CH3, C2H5 and m=2-6 (degree of polyglycolicity).As starting materials monomethyl and monoethyl ethers of polyethylene glycols of the formula R(OC2H4)nOH were used, where n=1-3.As reagents toluenesulfonyl chloride and methanesulfonyl chloride were used.
