However, its specific properties and uses would require further investigation and testing.
Check Digit Verification of cas no
The CAS Registry Mumber 188825-10-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,8,2 and 5 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 188825-10:
(8*1)+(7*8)+(6*8)+(5*8)+(4*2)+(3*5)+(2*1)+(1*0)=177
177 % 10 = 7
So 188825-10-7 is a valid CAS Registry Number.

Versatile Synthesis of Dihydroquinolines and Quinoline Quinones Using Cyclobutenediones. Construction of the Pyridoacridine Ring System
Zhang, Dawei,Llorente, Isidro,Liebeskind, Lanny S.
, p. 4330 - 4338 (2007/10/03)
1-BOC-2-lithio-1, 4-dihydropyridines were condensed with 3,4-disubstituted cyclobutenediones to produce 1,2-adducts. Neat thermolysis under oxygen-free conditions produced substituted 1,4-dihydroquinoline hydroquinones in which the tert-butoxy residue of the BOC group was displaced by a phenolic residue, generating an oxazolone ring that functioned to protect both rings of the dihydroquinoline hydroquinone from untimely oxidation. Oxidative aromatization with concomitant loss of the oxazolone ring was achieved using 2 equiv of o-chloranil in acetic acid and provided substituted quinoline quinones in good yields. By use of this strategy, a concise synthesis of the pyridoacridine ring system was achieved.
