Check Digit Verification of cas no

The CAS Registry Mumber 27665-39-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,6,6 and 5 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 27665-39:
(7*2)+(6*7)+(5*6)+(4*6)+(3*5)+(2*3)+(1*9)=140
140 % 10 = 0
So 27665-39-0 is a valid CAS Registry Number.

A 1,4-d disulfonic acid refined product and its solution preparation method

-

Paragraph 0030; 0031; 0032, (2017/02/09)

The invention relates to a preparation method of a 1,4-butyldisulfonic acid fine product and a solution thereof, belonging to the technical field of organic synthesis. The preparation method of the 1,4-butyldisulfonic acid fine product is characterized by comprising the following steps: carrying out acidifying reaction on sodium 1,4-butyldisulfate and hydrogen chloride gas in an organic alcohol solvent, removing the hydrogen chloride, crystallizing with organic acid to obtain the 1,4-butyldisulfonic acid crude product, recrystallizing the crude product in the organic acid to obtain the 1,4-butyldisulfonic acid fine product, and preparing the fine product into the solution which can be stored stably. The preparation method has the advantages of mild technological conditions, controllable refinement method, high yield, high content of the fine product, stable fine product solution. low production cost, low environmental pollution and high product stability, and is beneficial to industrialization.
