1084889-57-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1084889-57-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,8,4,8,8 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1084889-57:
(9*1)+(8*0)+(7*8)+(6*4)+(5*8)+(4*8)+(3*9)+(2*5)+(1*7)=205
205 % 10 = 5
So 1084889-57-5 is a valid CAS Registry Number.

Synthesis of glycyrrhetic acid derivatives
Yong,Wang,Aisa,Liu
, p. 194 - 196 (2008)
11-Deoxyglycyrrhetinic acid (DGA) (2) was produced by Clemmensen reduction of the C-11 carbonyl of 18β-glycyrrhetic acid (GA) (1). Four derivatives of GA and DGA (3a-3d) were synthesized. Their structures were elucidated using spectral data (IR, mass, su
