Check Digit Verification of cas no

The CAS Registry Mumber 15263-86-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,2,6 and 3 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 15263-86:
(7*1)+(6*5)+(5*2)+(4*6)+(3*3)+(2*8)+(1*6)=102
102 % 10 = 2
So 15263-86-2 is a valid CAS Registry Number.

Fluorine-directed Nazarov cyclizations 2: Regioselective synthesis of 5-trifluoromethyl-2-Cyclopentenones

Ichikawa, Junji,Fujiwara, Masaki,Okauchi, Tatsuo,Minami, Toni

, p. 927 - 929 (1998)

1-Trifluoromethylvinyl vinyl ketones are treated with trimethylsilyl trifluoromethanesulfonate in CH2Cl2-1,1,1,3,3,3-hexafluoro-2-propanol to afford 5-trifluoromethyl-2-cyclopentenones. Both acyclic and cyclic substrates furnish the corresponding cyclized products in good to excellent yields with defined placement of the endocyclic double bond due to the strong electronic effect exerted by the trifluoromethyl group.
