Check Digit Verification of cas no
The CAS Registry Mumber 2804-55-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,0 and 4 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2804-55:
(6*2)+(5*8)+(4*0)+(3*4)+(2*5)+(1*5)=79
79 % 10 = 9
So 2804-55-9 is a valid CAS Registry Number.

PROCESS FOR THE SYNTHESIS AND SEPARATION OF HYDROFLUOROOLEFINS
-
Page/Page column 12-14, (2008/12/07)
A process for the synthesis of fluorinated olefins of the formula CF3CF=CHX, wherein X is F or H comprising contacting hexafluoropropene with hydrogen chloride in the vapor phase, in the presence of a catalyst, at a temperature in the range from about 200 °C to about 350 °C, wherein the mole ratio of hydrogen chloride to hexafluoropropene is from about 2:1 to about 4:1, separating the 1-chloro-1,2,3,3,3-pentafluoro-1-propene, 1,1-dichloro-2,3,3,3-tetrafluoro-1-propene and hydrogen fluoride products from unreacted hexafluoropropene, and hydrogen chloride by distillation, hydrogenating either the 1-chloro-1,2,3,3,3-pentafluoro-1-propene, 1,1-dichloro-2,3,3,3-tetrafluoro-1-propene or mixture thereof over a catalyst, and dehydrochlorinating the said hydrogenation product to produce either 1225ye or 1234yf.
