113893-72-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 113893-72-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,8,9 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 113893-72:
(8*1)+(7*1)+(6*3)+(5*8)+(4*9)+(3*3)+(2*7)+(1*2)=134
134 % 10 = 4
So 113893-72-4 is a valid CAS Registry Number.

Synthesis of the trisaccharide portion of soyasaponin βg: Evaluation of a new glucuronic acid acceptor
Ple, Karen
, p. 1441 - 1454 (2007/10/03)
The synthesis of the trisaccharide portion of soyasaponin βg was successfully achieved using a new glucuronic acid acceptor: methyl 1-O-allyl-3,4-di-O-methoxymethyl-β-D-glucuronate (9). This compound and methyl 1-O-allyl-3,4-di-O-tert-butyldimethylsilyl-β
