Check Digit Verification of cas no
The CAS Registry Mumber 73936-80-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,9,3 and 6 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 73936-80:
(7*7)+(6*3)+(5*9)+(4*3)+(3*6)+(2*8)+(1*0)=158
158 % 10 = 8
So 73936-80-8 is a valid CAS Registry Number.

Paragraph 0015; 0016, (2017/03/08)
The invention relates to a preparation method of 2-cumyl-4-tert-octylphenol. The preparation method comprises the following steps: adding tert-octylphenol and a strongly-acidic cation exchange resin into a reactor, and heating to 90-140 DEG C; dropwisely adding alpha-methyl styrene; after the dropwise addition, continuing keeping the temperature at 90-140 DEG C to react; and after the reaction finishes, filtering to recover the strongly-acidic cation exchange resin, and rectifying the filtrate to obtain the 2-cumyl-4-tert-octylphenol. The preparation method is simple to operate. The catalyst can be separated from the reaction system only by simple filtration without acid washing, alkali washing, water washing or any other step capable of easily generating wastewater, and thus, is more environment-friendly. The raw material conversion rate is high, and the alpha-methyl styrene conversion rate can reach 99% or above. The product selectivity is high, and the 2-cumyl-4-tert-octylphenol selectivity is 99% or above. The catalyst can be repeatedly used and regenerated, and is suitable for industrialized clean production.
