Check Digit Verification of cas no

The CAS Registry Mumber 127-68-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 7 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 127-68:
54 % 10 = 4
So 127-68-4 is a valid CAS Registry Number.

Method for preparing sodium 3-nitrobenzene sulfonate and derivative thereof through chlorosulfonic acid sulfonation


Paragraph 0046-0059; 0062-0066, (2019/01/07)

The invention discloses a method for preparing sodium 3-nitrobenzene sulfonate and a derivative thereof through chlorosulfonic acid sulfonation. The method comprises the following steps: 1) putting anitrobenzene raw material and chlorosulfonic acid into a reaction container, heating to 90-150 DEG C, keeping the temperature, carrying out a sulfonation reaction, and discharging a hydrogen chloridegas generated in the reaction process outside the reaction system in time, wherein the mole ratio of the nitrobenzene raw material to the chlorosulfonic acid is 1:(0.4-0.6); 2) carrying out aftertreatment on the reaction liquid obtained in the step 1) by using soda, thereby obtaining the sodium 3-nitrobenzene sulfonate or the derivative thereof. By adopting the method, a reverse thinking mode is adopted, the amount of the chlorosulfonic acid is reduced till being smaller than that of the nitrobenzene, and then the small amount of the chlorosulfonic acid can be converted by using the excessiveamount of the nitrobenzene; therefore, the method disclosed by the invention has no problem of treating residual chlorosulfonic acid; in addition, the excessive nitrobenzene can be easily recycled andcirculated, the hydrogen chloride as a byproduct can be also easily separated and recycled.
