1439370-58-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1439370-58-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,9,3,7 and 0 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1439370-58:
(9*1)+(8*4)+(7*3)+(6*9)+(5*3)+(4*7)+(3*0)+(2*5)+(1*8)=177
177 % 10 = 7
So 1439370-58-7 is a valid CAS Registry Number.

Synthesis of coumarin/pyrrole-fused heterocycles and their photochemical and redox-switching properties
Lin, Chi-Hui,Yang, Ding-Yah
, p. 2802 - 2805 (2013/07/26)
Two coumarin/pyrrole-fused heterocycles were synthesized to investigate their photochemical and redox-switching properties. Photooxidation of the colorless diphenyl-substituted pyrrolocoumarin resulted in a distinct change to red and a sharp decrease in f
