Check Digit Verification of cas no

The CAS Registry Mumber 53859-14-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,8,5 and 9 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 53859-14:
(7*5)+(6*3)+(5*8)+(4*5)+(3*9)+(2*1)+(1*4)=146
146 % 10 = 6
So 53859-14-6 is a valid CAS Registry Number.

4,8-dihydroxy-1-Tetralone chemical synthesis method

-

Paragraph 0020; 0021, (2016/10/08)

The invention discloses a chemical synthesis method of 4,8- dihydroxyl-1-tetralone. The chemical synthesis method comprises the following steps: by taking 5-hydroxyl- tetralone as a raw material, firstly, adding NaBH4 to synthesize 5-hydroxyl-tetralol by taking methanol as a solvent, and adding benzoyl chloride to synthesize 1,5-dibenzoyl- tetrahydronaphthalene by taking pyridine as a solvent; then, adding benzene, diatomite, pyridinium dichromate and tert-butyl hydroperoxide to synthesize 4,8- dibenzoyl-1-tetralone; and finally, adding cesium carbonate to synthesize 4,8- dihydroxyl-1-tetralon by taking methanol as a solvent. The chemical synthesis method disclosed by the invention is simple in process, green and environmentally friendly and high in product purity which reaches 99.82%, and has a reaction total yield of 39-47%.
