Check Digit Verification of cas no
The CAS Registry Mumber 7149-20-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,4 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 7149-20:
(6*7)+(5*1)+(4*4)+(3*9)+(2*2)+(1*0)=94
94 % 10 = 4
So 7149-20-4 is a valid CAS Registry Number.

Paragraph 0023; 0024, (2016/10/08)
The invention relates to a preparation method for 3,3'-diamino-4,4'-dihydroxy diphenyl sulfone. The preparation method comprises the following steps: dissolving 3,3'-dinitro-4,4'-dichloro diphenyl sulfone in a polar solvent, dimethyl sulfoxide, adding a sodium hydroxide solution and reacting completely, then regulating pH to 1-2 and precipitating a solid to obtain 3,3'-dinitro-4,4'-dihydroxy diphenyl sulfone; and dissolving the 3,3'-dinitro-4,4'-dihydroxy diphenyl sulfone in a polar solvent, dimethyl sulfoxide, adding an ammonium chloride aqueous solution and reduced iron powders, carrying out thermal filtering after raw materials are reacted completely, washing filter cakes with hot dimethyl sulfoxide, combining filtrate, distilling under reduced pressure to obtain a mixed solution of the dimethyl sulfoxide and water, and drying to obtain the 3,3'-diamino-4,4'-dihydroxy diphenyl sulfone. The method has the advantages of high yield, easiness in operation, good repeatability and the like. Meanwhile, raw materials are easy to purchase, requirements on production equipment are low, and solvents can be reused.
