870765-38-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 870765-38-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,0,7,6 and 5 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 870765-38:
(8*8)+(7*7)+(6*0)+(5*7)+(4*6)+(3*5)+(2*3)+(1*8)=201
201 % 10 = 1
So 870765-38-1 is a valid CAS Registry Number.

Paragraph 0035; 0038-0039; 0044; 0047-0048; 0053; 0056-0057, (2019/01/21)

The invention relates to a preparation method of aripiprazole, and belongs to the technical field of preparation of raw material medicines. The preparation method comprises the following steps: carrying out a coupling reaction on 2,3-dichlorobromobenzene ued as a starting material and bis(2-chloroethyl)amine, carrying out a cyclization reaction on the obtained coupling reaction product and 4-amino-1-butanol, carrying out a substitution reaction on the obtained cyclization reaction product and thionyl chloride to obtain a chlorobutyl-substituted intermediate III, and further reacting the intermediate III with 3,4-dihydro-7-hydroxyl-2(1H)-quinolinone to form the aripiprazole. The preparation method has great advantages in reducing the use equivalent of every material and controlling the formation of a dimer, so the finished aripiprazole product with a high purity is well obtained.
