Check Digit Verification of cas no
The CAS Registry Mumber 104513-03-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,5,1 and 3 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 104513-03:
(8*1)+(7*0)+(6*4)+(5*5)+(4*1)+(3*3)+(2*0)+(1*3)=73
73 % 10 = 3
So 104513-03-3 is a valid CAS Registry Number.

Synthesis of tetracenomycins
Cameron,De Bruyn
, p. 5593 - 5596 (2007/10/02)
Tetracenomycins D, A2, B1 and B2 (2)-(5) have been synthesised for the first time, by an efficient, regioselective sequence based on cycloaddition methodology; the ambiguity that existed for tetracenomycins B1 and B2 has thereby been resolved in favour of structures (4a) and (5b) respectively.
