134774-70-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134774-70-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,7,7 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 134774-70:
(8*1)+(7*3)+(6*4)+(5*7)+(4*7)+(3*4)+(2*7)+(1*0)=142
142 % 10 = 2
So 134774-70-2 is a valid CAS Registry Number.

, 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.
