Check Digit Verification of cas no
The CAS Registry Mumber 24253-37-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,2,5 and 3 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 24253-37:
(7*2)+(6*4)+(5*2)+(4*5)+(3*3)+(2*3)+(1*7)=90
90 % 10 = 0
So 24253-37-0 is a valid CAS Registry Number.

-
Paragraph 0020, (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.
