Check Digit Verification of cas no

The CAS Registry Mumber 1132832-75-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,2,8,3 and 2 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1132832-75:
(9*1)+(8*1)+(7*3)+(6*2)+(5*8)+(4*3)+(3*2)+(2*7)+(1*5)=127
127 % 10 = 7
So 1132832-75-7 is a valid CAS Registry Number.

Preparation method of 2-(4-fluorophenyl)-5-[(5-bromo-2-methylphenyl)methyl]thiophene

-

Paragraph 0033; 0037; 0038, (2020/06/17)

The invention relates to the technical field of medicine synthesis, and particularly discloses a preparation method of 2-(4-fluorophenyl)-5-[(5-bromo-2-methylphenyl)methyl]thiophene. The preparation method comprises the following steps: by taking a nitrogen-doped carbon material loaded with transition metal as a catalyst, introducing hydrogen, and performing hydrogenation reduction on 2-methyl-5-bromophenyl-2-(4-fluorophenyl)thiophene ketone at 50-180 DEG C, thereby obtaining 2-(4-fluorophenyl)-5-[(5-bromo-2-methylphenyl)methyl]thiophene. The preparation method provided by the invention has the characteristics of the high product yield, high purity, the low cost, no toxicity and no pollution, and overcomes the defects in the traditional preparation process of 2-(4-fluorophenyl)-5-[(5-bromo-2-methylphenyl)methyl]thiophene.

Synthesis method of canagliflozin intermediate

-

, (2018/03/26)

The invention relates to a synthesis method of a canagliflozin intermediate. Concretely, succinyl oxide and fluorobenzene are used as starting raw materials to be prepared into the canagliflozin crucial intermediate of 2-(4-fluorophenyl)-5-[(5-halogen-2-methyl phenyl)methyl]thiophene through the steps of Friedel-Crafts acylation ring opening, thiophene ring preparation, Friedel-Crafts acylation coupling, reduction and the like. The cheap succinyl oxide is used for preparing the thiophene ring, so that the Suzuki coupling reaction and Grignard reaction are avoided; the use of heavy metal reagents of palladium and the like is avoided; the production process is simplified; the product yield and the quality are improved; the environment pollution is reduced; the production cost is reduced.
