Check Digit Verification of cas no

The CAS Registry Mumber 1259313-10-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,9,3,1 and 3 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1259313-10:
(9*1)+(8*2)+(7*5)+(6*9)+(5*3)+(4*1)+(3*3)+(2*1)+(1*0)=144
144 % 10 = 4
So 1259313-10-4 is a valid CAS Registry Number.

Pd-catalysed regioselective C-H functionalisation of 2-pyrones

Burns, Michael J.,Thatcher, Robert J.,Taylor, Richard J. K.,Fairlamb, Ian J. S.

supporting information; experimental part, p. 10391 - 10400 (2011/01/06)

A new synthetic methodology for the catalytic C-H functionalisation of 2-pyrones is described which proceeds regioselectively at the C3 position, mirroring the observed regioselectivity in 6π-electrocyclisation/oxidative aromatisation reactions of related
