Check Digit Verification of cas no

The CAS Registry Mumber 128259-76-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,2,5 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 128259-76:
(8*1)+(7*2)+(6*8)+(5*2)+(4*5)+(3*9)+(2*7)+(1*6)=147
147 % 10 = 7
So 128259-76-7 is a valid CAS Registry Number.

Novel process for the synthesis of 2-fluoro-1-olefins

-

, (2008/06/13)

A process for preparing 2-fluoro-1-olefins or terminal bis-beta-fluoro-olefins which comprises reacting an appropriate allyl or alpha-olefinated starting material with phenylselenyl chloride and silver fluoride, and then reacting the intermediate phenylselenyl fluoride compound with ozone, and further reacting the resulting phenylselenoxide compound with an appropriate amine, to yield the desired fluorinated compounds.

A new synthesis of 2-fluoro-1-olefins

McCarthy, James R.,Matthews, Donald P.,Barney, Charlotte L.

, p. 973 - 976 (2007/10/02)

The first examples of the addition of PhSeF to olefins to yield β-fluoro phenylselenides (2) are reported. β-Fluoro phenylselenides (2) obtained from terminal olefins were converted to the title vinyl fluorides 3 on treatment with ozone, whereas, 2 obtain
