Check Digit Verification of cas no
The CAS Registry Mumber 730993-62-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,3,0,9,9 and 3 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 730993-62:
(8*7)+(7*3)+(6*0)+(5*9)+(4*9)+(3*3)+(2*6)+(1*2)=181
181 % 10 = 1
So 730993-62-1 is a valid CAS Registry Number.

Rare Earth Metal Catalyzed C–F Bond Activation
Jaeger, Alma D.,Lentz, Dieter
, p. 1229 - 1233 (2018)
Cp3Ln (Ln = Ce, Nd, Sm, Er, Yb) are applied as precatalysts in the presence of LiAlH4 for the C–F bond activation of hexafluoropropene, 1,1,3,3,3-pentafluoropropene, trifluoropropene, chlorotrifluoroethene, and octafluorotoluene. 100 % conversion and TONs up to 155 could be observed for the hydrodefluorination reaction (HDF). For chlorotrifluoroethene hydrodefluorination occurs with high chemoselectivity favoring the C–F bond activation versus C–Cl bond activation.

Page/Page column 9, (2008/12/05)
A process is disclosed for making CF3CF=CH2 or mixtures thereof with CHF2CF=CHF. This process involves (a) reacting CHCI2CF2CF3, and optionally CHCIFCF2CCIF2, with H2 in the presence of a catalytically effective amount of a hydrogenation catalyst to form CH3CF2CF3 and, when CHCIFCF2CCIF2 is present, CH2FCF2CHF2; (b) dehydrofluorinating CH3CF2CF3, and optionally any CH2FCF2CHF2, from (a) to form a product mixture including CF3CF=CH2 and, if CH2FCF2CHF2 Js present, CHF2CF=CHF; and optionally (c) recovering CF3CF=CH2, or a mixture thereof with CHF2CF=CHF from the product mixture formed in (b) and/or (d) separating at least a portion of any CHF2CF=CHF in the product mixture formed in (b) from the CF3CF=CH2 in the product mixture formed in (b).
