Check Digit Verification of cas no
The CAS Registry Mumber 1569084-21-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,6,9,0,8 and 4 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1569084-21:
(9*1)+(8*5)+(7*6)+(6*9)+(5*0)+(4*8)+(3*4)+(2*2)+(1*1)=194
194 % 10 = 4
So 1569084-21-4 is a valid CAS Registry Number.

Neutral copper(i) dipyrrin complexes and their use as sensitizers in dye-sensitized solar cells
Hewat, Tracy E.,Yellowlees, Lesley J.,Robertson, Neil
, p. 4127 - 4136 (2014/03/21)
Heteroleptic neutral copper(i) dipyrrin complexes have been synthesised with the general formula [Cu(4,4′-(R)-6,6′-(CH3)- bipyridine)(dipyrrin)], R = CH3 or CO2Et, and H-dipyrrin is either 1,3,7,9-tetramethyldipyrromethene
