Check Digit Verification of cas no

The CAS Registry Mumber 148679-89-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,8,6,7 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 148679-89:
(8*1)+(7*4)+(6*8)+(5*6)+(4*7)+(3*9)+(2*8)+(1*9)=194
194 % 10 = 4
So 148679-89-4 is a valid CAS Registry Number.

Direct observation by 1H NMR of 4,5-benzoxepin-2,3-oxide and its surprisingly rapid ring-opening rearrangement to 1H-2-benzopyran-1- carboxaldehyde

Nauduri, Dhananjaya,Greenberg, Arthur

, p. 4789 - 4793 (2004)

The first unambiguous observation of an oxepin-2,3-oxide is reported. Between 5 and 10°C it rearranges rapidly to its isomer 1H-2-benzopyran-1- carboxaldehyde. In contrast, 2,3-oxides of monocyclic oxepins rearrange to stable, ring-opened dialdehydes or d
