The CAS Registry Mumber 1547397-90-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,4,7,3,9 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1547397-90:
(9*1)+(8*5)+(7*4)+(6*7)+(5*3)+(4*9)+(3*7)+(2*9)+(1*0)=209

Direct imine acylation for molecular diversity in heterocyclic synthesis

Unsworth, William P.,Coulthard, Graeme,Kitsiou, Christiana,Taylor, Richard J. K.

, p. 1368 - 1376 (2014/03/21)

Imines and carboxylic acids have been directly coupled using propylphosphonic acid anhydride and NEt(i-Pr)2 to give N-acyliminium ions, which were intramolecularly trapped with oxygen, nitrogen, sulfur, and carbon nucleophiles to provide a wide range of structurally diverse heterocycles.
