Check Digit Verification of cas no

The CAS Registry Mumber 1227781-75-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,7,7,8 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1227781-75:
(9*1)+(8*2)+(7*2)+(6*7)+(5*7)+(4*8)+(3*1)+(2*7)+(1*5)=170
170 % 10 = 0
So 1227781-75-0 is a valid CAS Registry Number.

Direct synthesis of trisubstituted isoxazoles through gold-catalyzed domino reaction of alkynyl oxime ethers

Ueda, Masafumi,Sato, Aoi,Ikeda, Yuki,Miyoshi, Tetsuya,Naito, Takeaki,Miyata, Okiko

supporting information; experimental part, p. 2594 - 2597 (2010/08/07)

Alkynyl oxime ether underwent a gold-catalyzed domino reaction involving cyclization and subsequent Claisen-type rearrangement to afford trisubstituted isoxazoles in a direct, efficient, and regioselective manner. The products were successfully applied to the synthesis of unusual heterocycles as an illustration of the potential utility of the reaction.
