Check Digit Verification of cas no

The CAS Registry Mumber 1422018-15-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,2,0,1 and 8 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1422018-15:
(9*1)+(8*4)+(7*2)+(6*2)+(5*0)+(4*1)+(3*8)+(2*1)+(1*5)=102
102 % 10 = 2
So 1422018-15-2 is a valid CAS Registry Number.

Direct synthesis of 4-fluoroisoxazoles through gold-catalyzed cascade cyclization-fluorination of 2-alkynone O-methyl oximes

Jeong, Yunkyung,Kim, Bom-I,Lee, Jae Kyun,Ryu, Jae-Sang

, p. 6444 - 6455 (2014/08/05)

A tandem protocol for the synthesis of fluorinated isoxazoles has been developed via catalytic intramolecular cyclizations of 2-alkynone O-methyl oximes and ensuing fluorination. The reactions proceed smoothly at room temperature in the presence of 5 mol
