Check Digit Verification of cas no

The CAS Registry Mumber 19742-90-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,7,4 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 19742-90:
(7*1)+(6*9)+(5*7)+(4*4)+(3*2)+(2*9)+(1*0)=136
136 % 10 = 6
So 19742-90-6 is a valid CAS Registry Number.

DOCK1-INHIBITING COMPOUND AND USE THEREOF

-

Paragraph 0152; 0244; 0245, (2021/10/07)

Provided is a compound that is usable as an active ingredient of an anticancer agent. Preferably provided is a compound that has DOCK1-inhibiting activity and exerts an anticancer effect based on the activity. A compound represented by the following formula (A) or a salt thereof: wherein X represents a carbon atom or a nitrogen atom; Y represents an oxygen atom, a hydroxy group, or a hydrocarbon group; R1 and R2 are different, and each represents a hydrogen atom or a group represented by the following formula (A-1): (wherein R6 represents a pyrrolidino group or a phenyl group, and n2 is 0 or 1) ; R3 represents -CO-R7 (wherein R7 is an alkoxy group, an alkyl group, or an alkylamino group), a 1,3-oxazole group, an alkylhydroxy group, a hydrogen atom, or an oxygen atom; R4 represents a hydrogen atom, an oxygen atom, or a hydrocarbon group in which one or more hydrogen atoms may be replaced by one or more substituents; R5 represents a halogen atom, a halogenated alkyl group, or a halogenated alkylthio group; and n1 is an integer of 0 to 5; and

Metal-free chalcogenation of cycloketone oxime esters with dichalcogenides

supporting information, (2021/06/15)

We report the metal-free chalcogenation of cycloketone oxime esters with dichalcogenides via a radical process. Because of the metal-free condition and use of readily accessible dichalcogenides, this method is an effective and green strategy for the synthesis of chalcogen-substituted butyronitrile.

Palladium-Catalyzed Picolinamide-Directed Benzylic C(sp3)?H Chalcogenation with Diaryl Disulfides and Diphenyl Diselenide

supporting information, p. 2947 - 2952 (2020/06/17)

The first palladium-catalyzed direct benzylic C(sp3)?H chalcogenation with diaryl disulfides and diphenyl diselenide has been established. The coupling reaction proceeds between the thioether radical and palladiumcycle intermediate. Picolinamide serves as an excellent directing group for the C?H activation of benzylic C(sp3)?H and can be easily removed. The current protocol exhibits a relatively broad substrate scope and high functional group compatibility. A mechanistic study indicates that palladium(IV) intermediate is probably formed during the course of the reaction. (Figure presented.).
