Check Digit Verification of cas no

The CAS Registry Mumber 1612838-57-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,2,8,3 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1612838-57:
(9*1)+(8*6)+(7*1)+(6*2)+(5*8)+(4*3)+(3*8)+(2*5)+(1*7)=169
169 % 10 = 9
So 1612838-57-9 is a valid CAS Registry Number.

Preparation method of monofluorobromoacetone derivative

-

Paragraph 0062-0071, (2020/06/16)

The invention relates to a preparation method of a monofluorobromoacetone derivative. The method comprises the following steps: mixing a compound as shown in a formula (1) with a catalyst, a ligand, alkali and a solvent, performing reacting with a compound as shown in a formula (2) under the protection of N2 until the reaction is complete, extracting and separating the obtained reaction solution to obtain the monofluorobromoacetone derivative as shown in a formula (3), wherein R1 is phenyl, substituted phenyl or heterocyclic ring; R2 is phenyl or substituted phenyl. Compared with the prior art, the method has the advantages of high reaction selectivity, milder conditions and shorter reaction time.

Palladium-catalyzed direct mono-α-arylation of α-fluoroketones with aryl halides or phenyl triflate

Zhou, Jun,Fang, Xiang,Shao, Tongle,Yang, Xueyan,Wu, Fanhong

, p. 54 - 62 (2016/10/05)

A palladium catalyzed Negishi-type α-arylation of α-fluoroketones with electron-rich and electron-deficient aryl halides or phenyl triflate has been developed. This direct mono-α-arylation method generate a variety of ternary α-aryl-α-monofluoroketones easily in good to excellent yields using XPhos as ligand and Cs2CO3as mild base.
