Check Digit Verification of cas no

The CAS Registry Mumber 1638755-19-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,8,7,5 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1638755-19:
(9*1)+(8*6)+(7*3)+(6*8)+(5*7)+(4*5)+(3*5)+(2*1)+(1*9)=207
207 % 10 = 7
So 1638755-19-7 is a valid CAS Registry Number.

1,2-N-migration in a gold-catalysed synthesis of functionalised indenes by the 1,1-carboalkoxylation of ynamides

Adcock, Holly V.,Langer, Thomas,Davies, Paul W.

, p. 7262 - 7266 (2014/06/23)

Unique α-hemiaminal ether gold carbene intermediates were accessed by a gold-catalysed 1,1-carboalkoxylation strategy and evolved through a highly selective 1,2-N-migration. This skeletal rearrangement gave functionalised indenes, and isotopic labelling c
