Check Digit Verification of cas no

The CAS Registry Mumber 1400908-78-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,0,9,0 and 8 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1400908-78:
(9*1)+(8*4)+(7*0)+(6*0)+(5*9)+(4*0)+(3*8)+(2*7)+(1*8)=132
132 % 10 = 2
So 1400908-78-2 is a valid CAS Registry Number.

Resin glycosides from the aerial parts of Operculina turpethum

Ding, Wenbing,Jiang, Zi-Hua,Wu, Ping,Xu, Liangxiong,Wei, Xiaoyi

experimental part, p. 165 - 174 (2012/10/08)

Three glycosidic acids, turpethic acids A-C, and two intact resin glycosides, turpethosides A and B, all having a common pentasaccharide moiety and 12-hydroxy fatty acid aglycones of different chain lengths, were obtained from the aerial parts of Operculina turpethum. Their structures were elucidated by spectroscopic analyses and chemical correlations. The aglycones were characterized as 12-hydroxypentadecanoic acid in two compounds, 12-hydroxyhexadecanoic acid in two other components, and 12-hydroxyheptadecanoic acid in the fifth compound, which were all confirmed by synthesis. The absolute configurations of these aglycones were all established as S by Mosher's method. These compounds represent the first examples of resin glycosides with a monohydroxylated 12-hydroxy fatty acid as an aglycone, and one compound is the first described resin glycoside having a hydroxylated C17 fatty acid as its aglycone.
