Check Digit Verification of cas no

The CAS Registry Mumber 819-71-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,1 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 819-71:
(5*8)+(4*1)+(3*9)+(2*7)+(1*1)=86
86 % 10 = 6
So 819-71-6 is a valid CAS Registry Number.

Synthesis of cleviolide and the scobinolides

Hollingworth, Gregory J.,Richecoeur, Alexandre M. E.,Sweeney, Joseph

, p. 2833 - 2836 (2007/10/03)

The palladium-catalysed cross-coupling reaction of 4-tributylstannylfuran-2(5H)-one 3 with 1-iodo-4-methylpent-3-en-1-yne 4a gives the natural product cleviolide; from this substance may be prepared both (Z)- and (E)-isomers of scobinolide.
