Check Digit Verification of cas no
The CAS Registry Mumber 219305-27-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,3,0 and 5 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 219305-27:
(8*2)+(7*1)+(6*9)+(5*3)+(4*0)+(3*5)+(2*2)+(1*7)=118
118 % 10 = 8
So 219305-27-8 is a valid CAS Registry Number.

Schrick, Petra,Geick, Klaus,Waldvogel, Siegfried R.
experimental part, p. 2211 - 2216 (2009/04/06)
2,6,7-Trihydroxyxanthen-3-ones are reliably prepared by a one-pot protocol using alkali peroxosulfates in the key step. NMR spectra in deuterated sodium hydroxide confirm the anticipated structures and allow the determination of the dye contents by an internal standard. Georg Thieme Verlag Stuttgart.
