Check Digit Verification of cas no

The CAS Registry Mumber 17387-48-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,3,8 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 17387-48:
(7*1)+(6*7)+(5*3)+(4*8)+(3*7)+(2*4)+(1*8)=133
133 % 10 = 3
So 17387-48-3 is a valid CAS Registry Number.

A thioether compound and its synthetic method and application (by machine translation)

-

Paragraph 0062; 0063; 0065, (2018/12/02)

The invention belongs to the technical field of sulfur-containing organic synthesis, discloses a thioether compound and its synthetic method and application. The vinyl ether compound is acetone, b of sulfur compounds, inorganic alkali and 18 - crown ether - 6 mixing, heating and stirring, in the inorganic alkali under the action of the catalyst, the reaction under air atmosphere, and then concentrated, purified made, the vinyl ether compound of molecular formula as formula (1) as shown: Wherein R1 And R2 Selected from hydrogen atom, alkyl, alkoxy, nitro, amino, hydroxy, halogen base, acyl, aryl or a heterocyclic group. The method can avoid the toxicity is relatively large of the methylene chloride and halogenated hydrocarbon such as methylene diiodide. The synthesis step is simple, convenient and easy operation, environment friendly and under a comparatively mild condition, have high conversion, the yield of the product can be as high as 96%. The thioether compound can be applied to the production of organic synthetic intermediates in the field. (by machine translation)
