Check Digit Verification of cas no

The CAS Registry Mumber 170745-08-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,0,7,4 and 5 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 170745-08:
(8*1)+(7*7)+(6*0)+(5*7)+(4*4)+(3*5)+(2*0)+(1*8)=131
131 % 10 = 1
So 170745-08-1 is a valid CAS Registry Number.

Palladium-catalyzed selective carbonylation of vinyl triflates in the presence of 2-iodophenols: A new route to 3-spiro-fused benzofuran-2(3H)-ones

Anacardio,Arcadi,D'Anniballe,Marinelli

, p. 831 - 836 (1995)

A convenient synthesis of 3-spiro-fused benzofuran-2(3H)-ones via palladium-catalyzed chemoselective carbonylation of vinyl triflates in the presence of o-iodophenols, followed by regioselective intramolecular Heck reaction, is described.
