Check Digit Verification of cas no

The CAS Registry Mumber 643728-77-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,3,7,2 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 643728-77:
(8*6)+(7*4)+(6*3)+(5*7)+(4*2)+(3*8)+(2*7)+(1*7)=182
182 % 10 = 2
So 643728-77-2 is a valid CAS Registry Number.

Synthesis and 19F NMR study of RF-oleic acid-F13

Buchanan, Gerald W.,Smits, Rufus,Munteanu, Elena

, p. 255 - 259 (2003)

A seven-step synthesis of Z-13,13,14,14,15,15,16,16,17,17,18,18, 18-tridecafluoro-octadec-9-enoic acid (oleic acid-F13) is reported. The key step is a Wittig reaction to form the C9-C10 double bond with a Z:E isomeric ratio greater than 20:1. The 19F nuclear magnetic resonance (NMR) spectrum is included and unambiguous assignments have been made with the aid of 19F-19F correlation NMR spectroscopy (COSY spectra).
