Check Digit Verification of cas no

The CAS Registry Mumber 14003-62-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,0,0 and 3 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 14003-62:
(7*1)+(6*4)+(5*0)+(4*0)+(3*3)+(2*6)+(1*2)=54
54 % 10 = 4
So 14003-62-4 is a valid CAS Registry Number.

1,2,3,3,3-PENTAFLUOROPROPENE PRODUCTION PROCESSES

-

Page/Page column 15, (2008/06/13)

A process is disclosed for making CF3CF=CHF. The process involves reacting CF3CCIFCCI2F with H2 in a reaction zone in the presence of a catalyst to produce a product mixture comprising CF3CF=CHF. The catalyst has a catalytically effective amount of palladium supported on a support selected from the group consisting of alumina, fluorided alumina, aluminum fluoride and mixtures thereof and the mole ratio of H2 to CF3CCIFCCI2F fed to the reaction zone is between about 1 :1 and about 5:1.. Also disclosed are azeotropic compositions of CF3CCIFCCI2F and HF and azeotropic composition of CF3CHFCH2F and HF.
