Check Digit Verification of cas no

The CAS Registry Mumber 1027255-60-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,2,5 and 5 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1027255-60:
(9*1)+(8*0)+(7*2)+(6*7)+(5*2)+(4*5)+(3*5)+(2*6)+(1*0)=122
122 % 10 = 2
So 1027255-60-2 is a valid CAS Registry Number.

Enantioselective, Catalytic Fluorolactonization Reactions with a Nucleophilic Fluoride Source

Woerly, Eric M.,Banik, Steven M.,Jacobsen, Eric N.

supporting information, p. 13858 - 13861 (2016/11/06)

The enantioselective synthesis of 4-fluoroisochromanones via chiral aryl iodide-catalyzed fluorolactonization is reported. This methodology uses HF-pyridine as a nucleophilic fluoride source with a peracid stoichiometric oxidant and provides access to lactones containing fluorine-bearing stereogenic centers in high enantio- and diastereoselectivity. The regioselectivity observed in these lactonization reactions is complementary to that obtained with established asymmetric electrophilic fluorination protocols.
