Check Digit Verification of cas no

The CAS Registry Mumber 23305-83-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,3,0 and 5 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 23305-83:
(7*2)+(6*3)+(5*3)+(4*0)+(3*5)+(2*8)+(1*3)=81
81 % 10 = 1
So 23305-83-1 is a valid CAS Registry Number.

A dichlorophenol synthesis method (by machine translation)

-

, (2019/06/05)

The present invention provides a kind of dichlorophenol synthetic method, comprises the following steps: S1, will be 1, 4 - dichlorobenzene alkylation reaction, to obtain the 1, 4 - dichloro - 2 - isopropyl benzene; or the 1, 3 - dichlorobenzene alkylation reaction, to obtain the 1, 3 - dichloro - 4 - cumene; or the 1, 2 - dichlorobenzene alkylation reaction, to obtain 1, 2 - dichloro - 4 - cumene; S2, to the 1, 4 - dichloro - 2 - cumene in alkyl, 1, 3 - dichloro - 4 - cumene in alkyl or 1, 2 - dichloro - 4 - alkyl in the cumene, through oxidation, the formula x structure obtained dichloro peroxide; S3, will the catalytic decomposition of the peroxide states two chlorine respectively, to obtain the dichlorophenol and acetone. The present invention provides a method for synthesizing of the dichlorophenol obtained the product content is high, the three waste less generation, mild reaction conditions, easy operation, low production cost.
