Check Digit Verification of cas no

The CAS Registry Mumber 110958-28-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,9,5 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 110958-28:
(8*1)+(7*1)+(6*0)+(5*9)+(4*5)+(3*8)+(2*2)+(1*8)=116
116 % 10 = 6
So 110958-28-6 is a valid CAS Registry Number.

HETEROANALOGOUS DEAZAPURINES VIA NOVEL 4 + 2 CYCLOADDITION REACTIONS OF KETENIMINES

Kollenz, Gert,Penn, Gerhard,Ott, Walter,Peters, Karl,Peters, Eva-Maria,Schnering, Hans Georg von

, p. 625 - 631 (2007/10/02)

The heterocyclic 2,3-diones 1 and the ketenimines 2 combine yielding heteroanalogous deazapurines 4, 6 and 7 partly having so far unknown molecular skeletons, which were made evident with aid of X-ray structure analyses (6b, 7a), IR- and 13C NMR measurements.The reaction pathways include 4 + 2 cycloaddition processes across the C=N-bond of the ketenimine, accompanied by several surprising rearrangements.These are the first examples observed of 4 + 2 cycloaddition reactions with ketenimines of to oxa-1,3-dienes.
