Check Digit Verification of cas no

The CAS Registry Mumber 131279-12-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,2,7 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 131279-12:
(8*1)+(7*3)+(6*1)+(5*2)+(4*7)+(3*9)+(2*1)+(1*2)=104
104 % 10 = 4
So 131279-12-4 is a valid CAS Registry Number.

Studies on the Constituents of Apocynacae Plants. Gas Chromatography-Mass Spectrometric Determination of New Flavanoid Triglycosides from the Leaves of Cerbera manghas L.

Sakushima, Akiyo,Hisada, Sueo,Ogihara, Yukio,Nishibe, Sansei

, p. 1219 - 1223 (2007/10/02)

Two new flavonol triglycosides, named manghaslin(I) and clitorin(II), were isolated from the leaves of Cerbera manghas L. (Apocynaceae).The structures of I and II were elucidated as quertecin-3-O-L-rhamnosyl-(12)-O6)> D-glucoside(I) and kaempferol-3-O-L-rhamnosyl-(12)-O-6)> D-glucoside(II), respectively, by chemical and gas chromatography-mass spectrometric studies.Keywords-Cerbera manghas L.; Apocynaceae; flavonol triglycerides; manghaslin; clitorin; gas chromatography-mass spectrometry; photohydrolysis; mass spectrum; methanolysis.
