Check Digit Verification of cas no
The CAS Registry Mumber 1717-59-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,1 and 7 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1717-59:
(6*1)+(5*7)+(4*1)+(3*7)+(2*5)+(1*9)=85
85 % 10 = 5
So 1717-59-5 is a valid CAS Registry Number.

Trifluoromethylation of haloarenes with a new trifluoro-methylating reagent Cu(O2CCF2SO2F)2
Zhao, Gang,Wu, Hao,Xiao, Zhiwei,Chen, Qing-Yun,Liu, Chao
, p. 50250 - 50254 (2016/06/15)
A new trifluoromethylating reagent Cu(O2CCF2SO2F)2, which easily decomposes to generate active CuCF3 species in DMF at room temperature, has been conveniently prepared from inexpensive starting materials on a large scale. This new reagent can be applied to efficiently trifluoromethylate a variety of haloarenes under mild conditions, providing good-to-excellent yields of the desired products.
Process for the production of trialkylsilyl(fluorosulfonyl)difluoroacetate

Page/Page column 3-4, (2008/06/13)
A process for the production of trialkylsilyl (fluorosulfonyl)difluoroacetate by contacting (fluorosulfonyl)difluoroacetyl fluoride with siloxane. The amount of (fluorosulfonyl)difluoroacetic acid by-product in trialkylsilyl(fluorosulfonyl)difluoroacetate is reduced by contacting said mixture with trialkylsilyl halide.
