Check Digit Verification of cas no

The CAS Registry Mumber 93978-69-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,9,7 and 8 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 93978-69:
(7*9)+(6*3)+(5*9)+(4*7)+(3*8)+(2*6)+(1*9)=199
199 % 10 = 9
So 93978-69-9 is a valid CAS Registry Number.

ADDITION OF 1-IODO-1,2-DIFLUORO-1,2,2-TRICHLOROETHANE AND 1-IODO-1,2,2-TRIFLUORO-1,2-DICHLOROETHANE TO TRIFLUOROCHLOROETHENE AND 1,2-DIFLUOROCHLOROETHENE

It was shown that the addition of 1-iodo-1,2-difluoro-1,2,2-trichloroethane to trifluorochloroethene and also the addition of 1-iodo-1,2-difluoro-1,2,2-trichloroethane and 1-iodo-1,2,2-trifluoro-1,2-dichloroethane to 1,2-difluorochloroethene lead to the formation of mixtures of telomers. 1-Chloro- and 1,4-dichloroperfluorobutadiene and 1,6-dichloroperfluorohexatriene were obtained from polyhalogenobutanes and hexanes by successive dehydrohalogenation, chlorination, and dechlorination.It was shown that 1,1,2,3,4-pentafluoropentachlorobutane and 1,1,2,3,4,5,6-heptafluoroheptachlorohexane form α-aryl-ω-chloroperfluoropolyenes in reaction with arylmagnesium bromides.
