Check Digit Verification of cas no
The CAS Registry Mumber 422-51-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 2 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 422-51:
(5*4)+(4*2)+(3*2)+(2*5)+(1*1)=45
45 % 10 = 5
So 422-51-5 is a valid CAS Registry Number.

19F nuclear magnetic resonance studies of halogenated propanes
Tanuma, T.,Ohnishi, K.,Okamoto, H.,Miyajima, T.,Morikawa, S.
, p. 259 - 284 (2007/10/02)
The relationship between 19F chemical shifts in halogenated propanes and their structures are elucidated using MNDO calculations to determine the population of rotamers.The pairs of atom gauche to a fluorine atom and van der Waals interaction between the two terminal substituents are responsible for the 19F chemical shifts.The differences among chemical shifts in diastereomers are also discussed in terms of the conformation of molecule.
