Check Digit Verification of cas no
The CAS Registry Mumber 623-90-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,2 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 623-90:
(5*6)+(4*2)+(3*3)+(2*9)+(1*0)=65
65 % 10 = 5
So 623-90-5 is a valid CAS Registry Number.

-
Paragraph 0025-0068, (2017/10/03)
The invention discloses a preparation method of maleic acid diethylene glycol monoethyl ether ester. According to the method, maleic anhydride and ethylene glycol monoethyl ether are taken as raw materials, and cyclohexane is taken as a water-carrying agent; catalytic esterification reaction is carried out in a tank reactor for 5-8h at the temperature of 90-110DEG C and under normal pressure; a titanium-silicon composite oxide is taken as a catalyst. The preparation method provided by the invention is high in catalytic preparation effect, and the maleic acid diethylene glycol monoethyl ether ester is high in yield and purity; the catalyst can be repeatedly recycled, and the catalytic efficiency is not obviously reduced when the catalyst is repeatedly recycled. Compared with the prior art, the method has outstanding substantial characteristics and remarkable progress.
