Check Digit Verification of cas no

The CAS Registry Mumber 301-19-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,0 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 301-19:
(5*3)+(4*0)+(3*1)+(2*1)+(1*9)=29
29 % 10 = 9
So 301-19-9 is a valid CAS Registry Number.

The final structure of robinin and biorobin and their total synthesis

Farkas,Vermes,Nogradi,Kalman

, p. 215 - 218 (2007/10/10)

Robinin has been proved by total synthesis and by methylation analysis using GC-MS to be kaempferol-3- O-(6-O-α-l-rhamnopyranosyl -β-d-galactopyranoside)-7-O-α-l-rhamnopyranoside and not, as claimed by Maksjutina et al., a mixture of 4 glycosides containing the 7-O-rhamnosyl moiety in the α- and β-furanoside as well as in the α- and β-pyranoside forms. The assumption that the 3-O-rhamnosido -galactose moiety contained furanoid rings was also disproved.
