111170-31-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111170-31-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,1,7 and 0 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 111170-31:
(8*1)+(7*1)+(6*1)+(5*1)+(4*7)+(3*0)+(2*3)+(1*1)=61
61 % 10 = 1
So 111170-31-1 is a valid CAS Registry Number.

SYNTHESIS AND CHEMICAL TRANSFORMATIONS OF CYCLOBUTANAPHTHALENE AND -ANTHRACENE DERIVATIVES
Ghera, Eugene,Maurya, Rakesh
, p. 709 - 712 (1987)
Cyclobutanaphthalene derivatives (2a-c) and an anthracene analog (2d) were prepared by a double annulation procedure from mono- and bicyclic precursors (1a-d).Compound 2a was further converted to 3-hydroxynaphtocyclobutene (10), to the novel quinone
