Check Digit Verification of cas no
The CAS Registry Mumber 6809-70-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,8,0 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6809-70:
(6*6)+(5*8)+(4*0)+(3*9)+(2*7)+(1*0)=117
117 % 10 = 7
So 6809-70-7 is a valid CAS Registry Number.

Synthesis of poly(ethylene oxide) approaching monodispersity
Maranski, Krzysztof,Andreev, Yuri G.,Bruce, Peter G.
, p. 6411 - 6413 (2014/06/24)
Polydispersity in polymers hinders fundamental understanding of their structure-property relationships and prevents them from being used in fields like medicine, where polydispersity affects biological activity. The polydispersity of relatively short-chain poly(ethylene oxide) [(CH 2CH2O2)n; PEO] affects its biological activity, for example, the toxicity and efficacy of PEOylated drugs. As a result, there have been intensive efforts to reduce the dispersity as much as possible (truly monodispersed materials are not possible). Here we report a synthetic procedure that leads to an unprecedented low level of dispersity. We also show for the first time that it is possible to discriminate between PEOs differing in only 1 ethylene oxide (EO) unit, essential in order to verify the exceptionally low levels of dispersity achieved here. It is anticipated that the synthesis of poly(ethylene oxide) approaching monodispersity will be of value in many fields where the applications are sensitive to the distribution of molar mass.
Synthesis of oligo(ethylene glycol) toward 44-mer
Ahmed, Saleh A.,Tanaka, Mutsuo
, p. 9884 - 9886 (2007/10/03)
A synthetic method for oligo(ethylene glycol) toward 44-mer (FW = 1956.35) is described. Reiteration of Williamson's ether synthesis and hydrogenation to remove protecting benzyl group affords desired oligo(ethylene glycol) toward 44-mer in moderate yields. The advantages in this method are use of commercially easily available materials as starting materials and procedures avoiding difficulty in purification of the products as much as possible.
