Check Digit Verification of cas no
The CAS Registry Mumber 68555-75-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,5,5 and 5 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 68555-75:
(7*6)+(6*8)+(5*5)+(4*5)+(3*5)+(2*7)+(1*5)=169
169 % 10 = 9
So 68555-75-9 is a valid CAS Registry Number.

, (2019/07/04)
The invention relates to an acrylic acid (N - methyl perfluoroalkyl sulfuryl amidogen) ethyl ester preparation method, comprising the following steps: S1. In order to perfluoroalkyl-fluoride and methylamine as raw materials, inorganic salt aqueous solution as the solvent, remain below the 4 °C temperature of reaction, shall be N - methyl perfluoroalkyl sulfonamide; S2. Under the action of the alkaline catalyst, S1 of the prepared N - methyl perfluoroalkyl sulfonamide with vinyl carbonate reaction, shall be N - hydroxyethyl - N - methyl perfluoroalkyl sulfonamide; S3. In the presence of hydroquinone, S2 prepared N - hydroxyethyl - N - methyl perfluoroalkyl sulfonamide with acrylic acid methyl ester exchange reaction, be acrylic acid (N - methyl perfluoroalkyl sulfuryl amidogen) acetic ester. The advantage is: in order to salt water solution is used as the preparation N - methyl perfluoroalkyl sulfonamide solvent, overcome in the prior art that use only the bias of the non-aqueous solvent, in the final waste water content greatly reduced COD, environment-friendly; yield and high purity.
