Check Digit Verification of cas no
The CAS Registry Mumber 24539-57-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,5,3 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 24539-57:
(7*2)+(6*4)+(5*5)+(4*3)+(3*9)+(2*5)+(1*7)=119
119 % 10 = 9
So 24539-57-9 is a valid CAS Registry Number.

Paragraph 0026; 0033-0035; 0041-0043; 0046-0048, (2020/08/22)
The invention discloses a synthesis method of an ultraviolet absorber UVA Plus. The method comprises the following steps: step 1, carrying out esterification reaction on phthalic anhydride and n-hexanol to obtain an intermediate monohexyl phthalate without other solvents, enabling the yield to reach over 99%, and enabling the intermediate to be directly subjected to the next step of reaction without refining; step 2, performing an acylation reaction on 3-hydroxy-N, N-diethylaniline and the intermediate monohexyl phthalate under the catalysis of a composite catalyst to prepare an ultraviolet absorber UVA Plus product, enabling the yield to be over 90%. The synthesis method has the advantages of easily available raw materials, easy refining and purification of the product, high yield, low production cost, and suitableness for industrial production.
