Check Digit Verification of cas no
The CAS Registry Mumber 5803-30-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,0 and 3 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5803-30:
(6*5)+(5*8)+(4*0)+(3*3)+(2*3)+(1*0)=85
85 % 10 = 5
So 5803-30-5 is a valid CAS Registry Number.

Paragraph 0018; 0021-0023; 0026-0039, (2021/01/28)
The invention provides a method for removing and recovering impurities in a methoxylamine hydrochloride synthesis reaction raw material, which belongs to the field of chemical engineering. The methodcomprises the following steps: (1) removal: adding an alkaline reagent into the methoxylamine hydrochloride synthesis reaction raw material, mixing, and separating methyl-removed impurities on one side; and (2) recovery: adding a methylation reagent into the methyl-removed impurities on one side separated in the step (1) to carry out a methylation reaction so as to obtain 2, 5-dimethoxypropiophenone, and recovering the 2, 5-dimethoxypropiophenone. According to the method, the characteristic that phenolic hydroxyl groups in impurities of a methoxylamine hydrochloride synthesis reaction raw material are weakly acidic is utilized, and the alkaline reagent is added to react with methyl-removed impurities on one side to form corresponding salt separation, so that impurities in the raw material2, 5-dimethoxypropiophenone are removed; after the separated impurity sodium salt is methylated again, 2, 5-dimethoxypropiophenone can be obtained again and recycled. The method is simpler and more convenient to operate, high in impurity removal rate and capable of effectively increasing the utilization rate of impurities in raw materials.
