134639-16-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134639-16-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,6,3 and 9 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 134639-16:
(8*1)+(7*3)+(6*4)+(5*6)+(4*3)+(3*9)+(2*1)+(1*6)=130
130 % 10 = 0
So 134639-16-0 is a valid CAS Registry Number.

Total synthesis of 4-demethoxyfeudomycinone C
Bertounesque,Florent,Monneret
, p. 270 - 272 (2007/10/02)
A synthesis of 4-demethoxyfeudomycinone C is described from the anthraquinone approach utilizing the carbon framework of (3R,5S)-3-hydroxy-5-hydroxymethyl-3-methyl-2-oxotetrahydrofuran. The latter is easily derived from α-D-isosaccharinic acid.
