Check Digit Verification of cas no

The CAS Registry Mumber 1228678-89-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,6,7 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1228678-89:
(9*1)+(8*2)+(7*2)+(6*8)+(5*6)+(4*7)+(3*8)+(2*8)+(1*9)=194
194 % 10 = 4
So 1228678-89-4 is a valid CAS Registry Number.

Preparation of fluoroalkenes via the Shapiro reaction: Direct access to fluorinated peptidomimetics

Yang, Ming-Hsiu,Matikonda, Siddharth S.,Altman, Ryan A.

supporting information, p. 3894 - 3897 (2013/09/02)

Fluoroalkenes represent a useful class of peptidomimetics with distinct biophysical properties. Current preparations of this functional group commonly provide mixtures of E- or Z-fluoroalkene diastereomers, and/or mixtures of nonfluorinated products. To directly access fluoroalkenes in good stereoselectivity, a Shapiro fluorination reaction was developed. Fluoroalkene products were accessed in one- or two-step sequences from widely available ketones. This strategy should be useful for the preparation of fluorinated analogs of peptide-based therapeutics, many of which would be challenging to prepare by alternate strategies.
