51415-02-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 51415-02-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,4,1 and 5 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 51415-02:
(7*5)+(6*1)+(5*4)+(4*1)+(3*5)+(2*0)+(1*2)=82
82 % 10 = 2
So 51415-02-2 is a valid CAS Registry Number.

Method for preparing panax japonicus saponin IVa butyl ester
-
Paragraph 0043; 0057-0058, (2020/02/10)
The invention discloses a method for preparing panax japonicus saponin IVa butyl ester. The method comprises the following steps: performing an indican reaction on 4,6-benzylidene protected glucose thioglycoside and 28-site glucose modified oleanolic acid so as to obtain a disaccharide oleanolic acid skeleton, performing an oxidation reaction with hydroxyl of which a protection group and glycol are cut off so as to obtain an intermediate, and enabling the intermediate to react with iodobutane, so as to obtain panax japonicum saponin IVa.
