Check Digit Verification of cas no

The CAS Registry Mumber 5308-54-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,0 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5308-54:
(6*5)+(5*3)+(4*0)+(3*8)+(2*5)+(1*4)=83
83 % 10 = 3
So 5308-54-3 is a valid CAS Registry Number.

REARRANGEMENTS OF REGIOISOMERIC 4-ISOXAZOLINES: THE NOVEL FORMATION OF ENAMINODERIVATIVES

Liguori, A.,Ottana, R.,Romeo, G.,Sindona, G.,Uccella, N.

, p. 1255 - 1266 (2007/10/02)

Regioisomeric 4-isoxazolines are formed by 1,3-dipolar cycloaddition of C-benzoyl-N-phenylnitrone to electron-deficient alkynes.The 4- and 5-substituted cycloadducts react in different modes under the same conditions yielding enaminoderivatives, via a nov
