Check Digit Verification of cas no

The CAS Registry Mumber 1041400-78-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,1,4,0 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1041400-78:
(9*1)+(8*0)+(7*4)+(6*1)+(5*4)+(4*0)+(3*0)+(2*7)+(1*8)=85
85 % 10 = 5
So 1041400-78-5 is a valid CAS Registry Number.

Synthesis of azepines by a gold-catalyzed intermolecular [4 + 3]-annulation

Shapiro, Nathan D.,Toste, F. Dean

supporting information; body text, p. 9244 - 9245 (2009/02/03)

A convenient gold(III)-catalyzed synthesis of azepines from the intermolecular annulation of propargyl esters and α,β-unsaturated imines is reported (19 examples, 55-95% yield). This formal [4 + 3]-cycloaddition reaction is proposed to proceed via a stepwise process involving intramolecular trapping of an allyl-gold intermediate. Copyright
