Check Digit Verification of cas no

The CAS Registry Mumber 889095-89-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,9,0,9 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 889095-89:
(8*8)+(7*8)+(6*9)+(5*0)+(4*9)+(3*5)+(2*8)+(1*9)=250
250 % 10 = 0
So 889095-89-0 is a valid CAS Registry Number.

β-Tosylethylazide: a useful synthon for preparation of N-protected 1,2,3-triazoles via click chemistry

Yap, Amy H.,Weinreb, Steven M.

, p. 3035 - 3038 (2006)

β-Tosylethylazide (TSE-N3), which can be prepared in one step from p-tolyl vinyl sulfone and sodium azide/H2SO4, undergoes metal-catalyzed 1,3-dipolar cycloadditions with alkynes to produce TSE-protected 1,2,3-triazoles. T
