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:
(7*1)+(6*9)+(5*1)+(4*1)+(3*1)+(2*8)+(1*7)=96
96 % 10 = 6
So 19111-87-6 is a valid CAS Registry Number.

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.

Preparation method of high purity 2-bromotriphenylene

-

Paragraph 0022, (2017/03/14)

The invention discloses a preparation method of high purity 2-bromotriphenylene. The preparation method comprises the following steps: step one, obtaining a first intermediate, second intermediate-(biphenyl-2-yl)-4,4,5,5-tetramethyl-1,3,2-boron dioxide; step two, drying the first intermediate, second intermediate-(biphenyl-2-yl)-4,4,5,5-tetramethyl-1,3,2-boron dioxide to obtain second intermediate-(4-bromophenyl)-1,1'-bibenzene; step three, adding the second intermediate-(4-bromophenyl)-1,1'-bibenzene, nitromethane, and iron trichloride into a container, heating to carry out reactions for three hours, cooling, adding water, and layering; condensing the organic phase until no water is left, adding ethanol, carrying out reflux, cooling to the room temperature, filtering, and drying to obtain the high purity 2-bromotriphenylene. The provided preparation method has the advantages of economy, simpleness, convenience, mild reaction conditions, good operation environment, and high yield.
