The CAS Registry Mumber 1416767-53-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,6,7,6 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1416767-53:
(9*1)+(8*4)+(7*1)+(6*6)+(5*7)+(4*6)+(3*7)+(2*5)+(1*3)=177
177 % 10 = 7
So 1416767-53-7 is a valid CAS Registry Number.

Direct imine acylation: Rapid access to diverse heterocyclic scaffolds

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

supporting information, p. 258 - 261 (2013/03/13)

A simple and efficient procedure to prepare a range of diverse heterocycles by the direct acylation of imines using a variety of functionalized benzoic acids is described. The methodology features a novel method for N-acyliminium ion generation followed by in situ intramolecular trapping by oxygen-, nitrogen-, sulfur-and carbon-based nucleophiles. Preliminary mechanistic studies, using ReactIR, are also reported.
