107672-17-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 107672-17-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,6,7 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 107672-17:
(8*1)+(7*0)+(6*7)+(5*6)+(4*7)+(3*2)+(2*1)+(1*7)=123
123 % 10 = 3
So 107672-17-3 is a valid CAS Registry Number.

A novel asymmetric synthesis of tritium and carbon-14 labeled (R)-ibuprofen
Zhang, Yinsheng,Hong, Yang,Huang, Che C.,Belmont, Daniel
, p. 237 - 244 (2007/10/03)
An efficient asymmetric synthesis of tritium and carbon-14 labeled R-ibuprofen was achieved in good overall yield (15% and 47%, respectively) and excellent enantiomerical excess (>98% e.e.), using (4R, 5S)-4-methyl-5- phenyl-2-oxazolidinone as a chiral au
