1310563-89-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1310563-89-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,0,5,6 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1310563-89:
(9*1)+(8*3)+(7*1)+(6*0)+(5*5)+(4*6)+(3*3)+(2*8)+(1*9)=123
123 % 10 = 3
So 1310563-89-3 is a valid CAS Registry Number.

Synthesis of α-CN and α-CF3 N-heterocycles through tandem nucleophilic additions
Han, Junbin,Xu, Bo,Hammond, Gerald B.
, p. 3450 - 3453 (2011/08/07)
Using a readily available secondary aminoalkyne as starting material, a powerful strategy was discovered to prepare precursors of biologically important unnatural cyclic aminoacids and fluorinated N-heterocycles with important ring sizes (e.g., 5-7) in a
