Check Digit Verification of cas no

The CAS Registry Mumber 19111-87-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,1,1 and 1 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 19111-87:
96 % 10 = 6
So 19111-87-6 is a valid CAS Registry Number.

Preparation method of triphenylene derivative


, (2021/03/31)

The invention relates to the field of organic chemistry, and in particular, relates to a preparation method of a triphenylene derivative. The invention provides the preparation method of the triphenylene derivative, wherein the method comprises the step: carrying out cyclization reaction on a compound represented by a formula 4 in the presence of acid, an initiator and an oxidant to provide a compound represented by a formula 5. According to the preparation method of the triphenylene derivative, provided by the invention, arylation reaction is carried out by using the acid and the oxidant, sothat side reactions generated in the reaction are few, the overall conversion rate of the reaction is high, and the raw materials are economical and practical; and in addition, the whole reaction route has high reaction yield and is convenient for industrial production and operation, and good industrialization prospects are realized.

Preparation method of 2-Bromotriphenylene


Paragraph 0028-0029, (2019/08/03)

The invention discloses a preparation method of 2-bromotriphenylene. The preparation method comprises the following steps: with biphenyl-2-boric acid and 2-iodine-4-bromonitrobenzene as raw materials,carrying out reflux reaction for 12 hours under the catalysis of tetrakis(triphenylphosphine)palladium, thereby obtaining 5-bromo-2-nitro-1,1'':2',1''-terphenyl after treatment; and mixing obtained 5-bromo-2-nitro-1,1':2',1''-terphenyl and ethanol, and then adding 80% of hydrazine hydrate, thereby obtaining 5-bromo-2-amino-1,1':2',1''-terphenyl under the catalysis of anhydrous ferric chloride andactivated carbon. The preparation method has the advantages that the target compound can be prepared from cheap and easily-available raw materials through three steps of reaction, and the total yieldof the product is up to 61%; the process is simple in operation and high in safety, so that the method is suitable for large-scale production; the purification operation is simple and is free of thegeneration of dibromo or tribromo byproducts, and the product purity is as high as 99% or above, so that the market competitiveness of the product is improved.
