4058-26-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4058-26-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,5 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4058-26:
(6*4)+(5*0)+(4*5)+(3*8)+(2*2)+(1*6)=78
78 % 10 = 8
So 4058-26-8 is a valid CAS Registry Number.

Using the same and a silane compound or multiple single molecular composition for forming molecular layer

-

Paragraph 0033; 0034, (2016/10/17)

[Problem] To provide a novel silane compound and a composition for formation of a monolayer or a multilayer on a substrate. [Solution] A composition for formation of a monolayer or a multilayer containing a silane compound represented by formula (1A) or formula (1B), and an organic solvent. [Chem 1] [In the formulae, each R1 independently represents a methyl group or an ethyl group, each X independently represents a C1-10 linking group, Z represents a phthalic imide group, a maleimide group, or a succinic imide group which may have at least one substituent, each Ar independently represents a phenyl group or a naphthyl group, and the linking group represented by X may contain at least one oxygen atom or sulfur atom in the main chain, and when the Ar is a phenyl group, the phenyl group may have at least one substituent.]

Dioxygen mediated hydroacylation of vinyl sulfonates and sulfones on water

supporting information; experimental part, p. 133 - 135 (2010/04/01)

Herein we report a mild, facile method for the preparation of 1,4-keto-sulfonates and sulfones on water. Further synthetic manipulations can result in products that are not readily accessed by hydroacylation of electron rich alkenes.
