Check Digit Verification of cas no
The CAS Registry Mumber 145439-11-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,4,3 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 145439-11:
(8*1)+(7*4)+(6*5)+(5*4)+(4*3)+(3*9)+(2*1)+(1*1)=128
128 % 10 = 8
So 145439-11-8 is a valid CAS Registry Number.

Preparation and palladium-catalysed cross-coupling reactions of 3-and 4-tributylstannylfuran-2(5H)-ones
Hollingworth, Gregory J.,Perkins, Gemma,Sweeney, Joseph
, p. 1913 - 1919 (1996)
Stannylfuranones 1 and 2 were prepared by ipso radical desulfurative stannylation of phenylsulfanylfuranones 3 and 16. Compounds 1 and 2 underwent Stille coupling reactions with aryl iodides to give 3- and 4-arylfuran-2(5H)-ones.
