Check Digit Verification of cas no

The CAS Registry Mumber 21443-88-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,4,4 and 3 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 21443-88:
(7*2)+(6*1)+(5*4)+(4*4)+(3*3)+(2*8)+(1*8)=89
89 % 10 = 9
So 21443-88-9 is a valid CAS Registry Number.

CYCLOADDITION DES METHYLAZIDE ET PHENYLAZIDE AU β-NITROSTYRENE ET AU NITROPROPENE HOMOLOGUE

Cailleux, P.,Piet, J. C.,Benhaoua, H.,Carrie, R.

, p. 45 - 52 (2007/10/03)

Phenylazide and methylazide reacts with title olefines and gives two isomeric triazoles without nitro group, and 4-nitro-1,2,3 triazole.The isomerisation of starting alkenes explains the formation of isomeric triazoles.Oxydation of amino-nitro-diazocompounds in equilibrium with 1,2,3 triazolines leads to 4-nitro-1,2,3 triazoles.
