Check Digit Verification of cas no
The CAS Registry Mumber 17624-08-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,6,2 and 4 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 17624-08:
(7*1)+(6*7)+(5*6)+(4*2)+(3*4)+(2*0)+(1*8)=107
107 % 10 = 7
So 17624-08-7 is a valid CAS Registry Number.

Preparation method of aromatic sulfonic acid compound
-
Paragraph 0021, (2016/11/17)
The invention discloses a preparation method of an aromatic sulfonic acid compound, and aims to provide the preparation method of the aromatic sulfonic acid compound, wherein the method is simple in process, low in equipment requirements, high in capacity, wide in raw material sources and small in environmental influence. The method is characterized by comprising the steps: with a starting material aromatic amine compound, dissolving in an acid, carrying out a diazotization reaction with sodium nitrite to prepare a diazocompound; carrying out a reaction of a catalyst cuprous salt with a thionyl chloride aqueous solution, and carrying out a sulfonylation reaction with the prepared diazocompound to obtain an aromatic sulfonyl chloride compound or an aromatic sulfonyl chloride hydrochloride compound, next hydrolyzing to obtain a crude product aromatic sulfonic acid compound, finally purifying through a beating way by an acidic solvent and an alcohol solution, and thus obtaining the high-purity aromatic sulfonic acid compound. The method is friendly to environment, has certain cost advantages, avoids use of more expensive aromatic thiol compounds as starting materials, and is beneficial for industrial production.
