Check Digit Verification of cas no

The CAS Registry Mumber 60027-48-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,0,2 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 60027-48:
(7*6)+(6*0)+(5*0)+(4*2)+(3*7)+(2*4)+(1*8)=87
87 % 10 = 7
So 60027-48-7 is a valid CAS Registry Number.

Synthesis of γ-benzopyranone by TfOH-promoted regioselective cyclization of o-alkynoylphenols

Yoshida, Masahito,Fujino, Yuta,Doi, Takayuki

, p. 4526 - 4529 (2011/10/09)

Regioselective cyclization of o-alkynoylphenols forming γ-benzopyranones has been demonstrated. Trifluoromethanesulfonic acid (TfOH) induced 6-endo cyclization of o-alkynoylphenols without forming 5-exo cyclized benzofuranone derivatives to provide the corresponding γ-benzopyranones in high yields.
