Check Digit Verification of cas no

The CAS Registry Mumber 109872-93-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,8,7 and 2 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 109872-93:
(8*1)+(7*0)+(6*9)+(5*8)+(4*7)+(3*2)+(2*9)+(1*3)=157
157 % 10 = 7
So 109872-93-7 is a valid CAS Registry Number.

Platinum(II) photo-catalysis for highly selective difluoroalkylation reactions

Zhong, Jian-Ji,Yang, Chen,Chang, Xiao-Yong,Zou, Chao,Lu, Wei,Che, Chi-Ming

, p. 8948 - 8951 (2017)

The platinum(ii) photo-catalyzed difluoroalkylation of cinnamic acids and alkynes for selective construction of E-,Z-difluoroalkyl alkenes and difluoroalkyl alkenyl iodides, respectively, were achieved under mild conditions. The high efficiency, good substrate scope and high selectivity altogether highlight the prospect of Pt(ii) photocatalysts in visible-light-driven organic transformation reactions.

N-heterocyclic carbene (NHC) catalyzed synthesis of α,α- difluoro esters

Dong, Xiuqin,Zhao, Yu-Ming,Sun, Jianwei

supporting information, p. 1221 - 1224 (2013/07/11)

A process for the synthesis of α,α-difluoro esters by NHC-catalyzed fluorination is described. The internal redox process exhibits good efficiency, selectivity, and functional-group compatibility. It provides an alternative strategy for the formation of the useful gem-difluoromethylene unit in organic molecules. Georg Thieme Verlag Stuttgart. New York.

Enantioselective synthesis of β,γ-unsaturated α-fluoroesters catalyzed by N-heterocyclic carbenes

Zhao, Yu-Ming,Cheung, Man Sing,Lin, Zhenyang,Sun, Jianwei

, p. 10359 - 10363 (2012/11/14)

NHC meets F: NHC-bound enolates undergo a catalytic asymmetric fluorination reaction to β,γ-unsaturated α-fluoroesters, which are obtained with good efficiency and stereoselectivity (see scheme, NFSI=N- fluorobenzenesulfonimide). The strategy overcomes possible challenges, such as fluorination in the γ position and difluorination. Experimental evidence combined with DFT calculations provides insight into the reaction mechanism. Copyright

SYNTHESIS OF 2,2-DIFLUOROESTERS BY IODODIFLUOROACETATE-COPPER WITH ORGANIC HALIDES

Taguchi, Takeo,Kitagawa, Osamu,Morikawa, Tsutomu,Nishiwaki, Tohru,Uehara, Hideya,et al.

, p. 6103 - 6106 (2007/10/02)

C-C bond formation through reactions of iododifluoroacetate-copper with various organic halides in aprotic solvent proceeds effectively to give 2,2-difluoroesters in good yield.With alkenyl iodides, these reactions are stereospecific.
