Check Digit Verification of cas no
The CAS Registry Mumber 223745-04-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,3,7,4 and 5 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 223745-04:
(8*2)+(7*2)+(6*3)+(5*7)+(4*4)+(3*5)+(2*0)+(1*4)=118
118 % 10 = 8
So 223745-04-8 is a valid CAS Registry Number.

5-amino-N-substituted benzimidazolone synthetic method
-
, (2017/02/24)
The invention discloses a synthesis method of 5-amonio-N-substituted benzimidazolone. The synthesis method is characterized by comprising the following steps of: (1) dropwise adding amine to an alcohol solvent of 2,4-dinitrochlorobenzene at a room temperature to be reacted for 0.5 hour to 2hours at a backflow temperature, and recrystallizing a product to obtain an N-substituted phenylamine; and (2), adding N-substituted phenylamine, sulphur, dimethylformamide, ammonium formate and potassium carbonate into water in a high-pressure reaction kettle to be reacted for 2 hours to 5hours under the condition of 160 to 200 DEG C, cooling the product to the room temperature, releasing the pressure to the atmospheric pressure, adding hydrazine hydrate and active carbon catalyst loaded with metal salt, heating to 60 to 100 DEG C to be reacted for 2 hours to 3hours, thermally filtering the product, steaming and drying the solvent, and recrystallizing the product to obtain the 5-amonio-N-substituted benzimidazolone. The reaction route is short, the reaction is simple, and the yield of the prepared product is high.
