493012-13-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 493012-13-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,3,0,1 and 2 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 493012-13:
(8*4)+(7*9)+(6*3)+(5*0)+(4*1)+(3*2)+(2*1)+(1*3)=128
128 % 10 = 8
So 493012-13-8 is a valid CAS Registry Number.

Synthesis of a pentasaccharide derivative corresponding to a triterpenoid saponin isolated from Spergularia ramosa
Gu, Guofeng,Du, Yuguo
, p. 2075 - 2079 (2007/10/03)
A highly convergent and regioselective glycosylation strategy has been employed for the synthesis of a hetero-pentasaccharide that corresponds to the major sugar chain of a saponin isolated from herbaceous plant, Spergularia ramosa.
