Check Digit Verification of cas no

The CAS Registry Mumber 883036-77-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,3,0,3 and 6 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 883036-77:
(8*8)+(7*8)+(6*3)+(5*0)+(4*3)+(3*6)+(2*7)+(1*7)=189
189 % 10 = 9
So 883036-77-9 is a valid CAS Registry Number.

On the synthesis of fused thiazolo[5,4-d]isoxazoles and a novel rearrangement involving conversion of 5(4H)-isoxazolones to 4(5H)-isoxazolones

Chande,Joshi

, p. 403 - 409 (2007/10/03)

The interaction of 4-bromo-3-substituted-(4H)-isoxazol-5-ones (1) with alkyl/aryl thiocarbamides (2), 4-alkyl/aryl thiosemicarbazides (7) and 2, 4-disubstituted thiosemicarbazides (12) afford 5-alkyl/ arylamino-3-substituted-thiazolo [5, 4-d]isoxazoles (3) and 6-amino/anilino-5-alkyl/arylimino-3-substituted-thiazolo[5, 4-d]isoxazoles respectively. An alternate unambiguous one step synthesis is described. The compounds have been characterised by chemical reactions and spectral data.
