Check Digit Verification of cas no

The CAS Registry Mumber 1287769-02-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,7,7,6 and 9 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1287769-02:
(9*1)+(8*2)+(7*8)+(6*7)+(5*7)+(4*6)+(3*9)+(2*0)+(1*2)=211
211 % 10 = 1
So 1287769-02-1 is a valid CAS Registry Number.

Iodocyclization of hydroxylamine derivatives based on the control of oxidative aromatization leading to 2,5-dihydroisoxazoles and isoxazoles

Okitsu, Takashi,Sato, Kana,Potewar, Taterao M.,Wada, Akimori

, p. 3438 - 3449 (2011/06/26)

An efficient method for the synthesis of 2,5-dihydroisoxazoles and isoxazoles using iodocyclization of N-alkoxycarbonyl O-propargylic hydroxylamines has been developed. 2,5-Dihydro-4-iodoisoxazole underwent the cross-coupling reactions without aromatization to afford polyfunctionalized 2,5-dihydroisoxazoles. This process was applied to the preparation of valdecoxib and its 2,5-dihydro-derivative.
