Check Digit Verification of cas no

The CAS Registry Mumber 23949-66-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,9,4 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 23949-66:
(7*2)+(6*3)+(5*9)+(4*4)+(3*9)+(2*6)+(1*6)=138
138 % 10 = 8
So 23949-66-8 is a valid CAS Registry Number.

Page/Page column 5-7, (2019/10/29)

The invention relates to an ultraviolet-absorbing agent preparation method, comprises the following steps: (1) D. amide esters intermediate synthesis: to oxalyl chloride ethyl ester and O-ethyl aniline as the raw material, the oxalyl chloride ethyl ester dissolved in a solvent, heating the stirring, then instillment neighbour ethyl aniline, after the reaction water elution solvent, to obtain D. amide esters intermediate; (2) N - (2 - ethoxy) - N' - (4 - ethyl-phenyl) - ethylenediamine amide product synthesis: in order to O-phenetidine and steps (1) obtained in the D. amide esters intermediate as raw materials, to Lewis base as catalyst, the temperature of the stirring, the reaction after 120 - 170 °C lower, boil off ethanol byproducts, cooling, is poured into the methanol stirring and dissolving, filtering out the insoluble matter, the temperature crystallization mother liquor, filtration, and dried to obtain the product. The preparation method, the process is simple, low requirements on equipment; the product has high purity, high yield, three wastes, environmental protection, low production cost, is suitable for industrial production.
