Check Digit Verification of cas no
The CAS Registry Mumber 13161-99-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,1,6 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 13161-99:
(7*1)+(6*3)+(5*1)+(4*6)+(3*1)+(2*9)+(1*9)=84
84 % 10 = 4
So 13161-99-4 is a valid CAS Registry Number.

-
Paragraph 0027-0032, (2019/07/04)
The invention discloses a N, inter-N' - phenylene bismaleimide preparation method, which belongs to the technical field of fine chemicals. The raw material is toluene, maleic anhydride and the polymerization inhibitor, heated to 40 - 60 °C dissolve; the metaphenylene diamine dissolved in strong polar solvent then drop added in a reaction vessel, and milling after thermal insulation, adding catalyst heating temperature to reflux, until no more water is stopped when the reaction is separated out; the reaction cooling after crystallization, filtered, washed with water, to obtain pale yellow solid N, between the N' - phenylene bismaleimide. The invention two-step reaction in the same reaction in the container, does not need to separation and purification of the intermediate product, its synthesis process is simple in operation, the working environment is obviously improved. The sold product liquid chromatography the content of 75% -80%, for the production of this invention liquid chromatography content can be up to 90% or more, the purity is higher than current commercial products.
