Check Digit Verification of cas no
The CAS Registry Mumber 81684-80-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,6,8 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 81684-80:
(7*8)+(6*1)+(5*6)+(4*8)+(3*4)+(2*8)+(1*0)=152
152 % 10 = 2
So 81684-80-2 is a valid CAS Registry Number.

The invention discloses a synthesis method of N-methyl-1,2-benzenediamine dihydrochloride. The synthesis method is characterized by comprising the following steps that 1, o-chloronitrobenzene and a monomethylamine aqueous solution are subjected to a sealing reaction, after the reaction is completed, cooling, standing and layering are conducted, and a lower-layer oil phase is collected to obtain N-methyl-2-nitroaniline; 2, a catalyst is added to a mixed solution of ethyl alcohol and the N-methyl-2-nitroaniline obtained in step 1, after mixing and heating, hydrazine hydrate is slowly dropwise added to the mixed solution, and after drop addition is completed, a heat preservation reaction is conducted; after the reaction is completed, suction filtration is conducted, and a suction filtration mother solution is reserved to obtain N-methyl-o-phenylenediamine; 3, liquid caustic soda, water and EDTA are added to the N-methyl-o-phenylenediamine obtained in step 2 for mixing, after cooling is conducted, dichloromethane is added, stirring, extraction, standing and layering are conducted, a lower-layer oil phase is collected, and through separation and purification, the target product N-methyl-1,2-benzenediamine dihydrochloride is obtained. The N-methyl-1,2-benzenediamine dihydrochloride product prepared through the method has high purity and few impurities and can be widely applied to the field of intermediate synthesis of a medicine tishamitan for reducing the blood pressure.
