Check Digit Verification of cas no

The CAS Registry Mumber 1402140-89-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,2,1,4 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1402140-89:
(9*1)+(8*4)+(7*0)+(6*2)+(5*1)+(4*4)+(3*0)+(2*8)+(1*9)=99
99 % 10 = 9
So 1402140-89-9 is a valid CAS Registry Number.

Copper-catalyzed synthesis of trisubstituted isoxazoles via a cascade cyclization-migration process

Ueda, Masafumi,Sugita, Shoichi,Sato, Aoi,Miyoshi, Tetsuya,Miyata, Okiko

, p. 9344 - 9351,8 (2012/12/11)

An atom-economical, catalytic, and regioselective synthesis of 3,4,5-trisubstituted isoxazoles has been successfully developed. Treatment of O-arylmethyl alkynyl oxime ethers with 5 mol % of Cu(OTf)2 in chlorobenzene at reflux gave 4-arylmethylisoxazoles in good to excellent yields via the sequential intramolecular addition of the oxime moiety to the alkyne with subsequent 1,3-migration of the arylmethyl group.
