Check Digit Verification of cas no
The CAS Registry Mumber 69114-99-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,1,1 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 69114-99:
(7*6)+(6*9)+(5*1)+(4*1)+(3*4)+(2*9)+(1*9)=144
144 % 10 = 4
So 69114-99-4 is a valid CAS Registry Number.

A diterpenoid sulphate and flavonoids from Wedelia asperrima
Calanasan, Cleofe A.,MacLeod, John K.
, p. 1093 - 1099 (2007/10/03)
A 4'-O-sulphated analogue of wedeloside, a new flavanone, 7,4'- dihydroxy-8,3'-dimethoxyflavanone and its related chalcone, together with the 4'-O-β-D-glucopyranoside of the latter, and a number of known compounds were isolated from the aerial parts of Wedelia asperrima. Their structures were established by spectroscopic techniques and by synthesis of the flavanone and chalcone.
