3119-65-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3119-65-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,1 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3119-65:
(6*3)+(5*1)+(4*1)+(3*9)+(2*6)+(1*5)=71
71 % 10 = 1
So 3119-65-1 is a valid CAS Registry Number.

Method for synthesizing 4,4'-thiodibenzenethiol

-

Paragraph 0033; 0034; 0035; 0042; 0043; 0046; 0047, (2017/08/29)

The invention discloses a method for synthesizing 4,4'-thiodibenzenethiol. The method comprises the following steps: by taking phenyl sulfide as an initial raw material, reacting with chlorosulfonic acid so as to obtain 4,4'-bis(chlorosulfonyl)phenyl sulfide; reducing with glacial acetic acid so as to obtain 4,4'-bis(ethanethioate)phenyl sulfide under the actions of red phosphorus and iodine; hydrolyzing so as to obtain crude 4,4'-thiodibenzenethiol; and finally, recrystallizing, thereby obtaining the high-quality 4,4'-thiodibenzenethiol. According to the method disclosed by the invention, raw materials are easily available, the process is advanced and the industrial production is convenient.
