Check Digit Verification of cas no

The CAS Registry Mumber 80681-48-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,6,8 and 1 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 80681-48:
(7*8)+(6*0)+(5*6)+(4*8)+(3*1)+(2*4)+(1*8)=137
137 % 10 = 7
So 80681-48-7 is a valid CAS Registry Number.

CHEMICAL STUDIES OF ANGELICA JAPONICA A. GRAY. I. ON THE CONSTITUENTS OF THE ETHYL ACETATE EXTRACT OF THE ROOT

Baba, Kimiye,Hata, Kiyoshi,Kimura, Yoshiyuki,Matsuyama, Youko,Kozawa, Mitsugi

, p. 2565 - 2570 (2007/10/02)

The dried roots of Angelica japonica A.Gray (Umbelliferae) afforded three new chromones (VI, VIII and IX) together with six known chromones (I-V and VII) and fourteen known coumarins (X-XXIII) which were identified by comparison with authentic samples.The structure of VI, VIII and IX were established as (3S)-2,2-dimethyl-3,5-dihydroxy-8-hydroxymethyl-3,4-dihydro-2H,6H-benzodipyran-6-one, (3S)-2,2-dimethyl-3-β-D-glucosyloxy-5-hydroxy-8-methyl-3,4-dihydro-2H,6H-benzodipyran-6-one (sec-O-glucosylhamaudol) and (2S)-2-(1-hydroxy-1-methylethyl)-4-methoxy-7-β-D-glucosyloxymethyl-2,3-dihydro-5H-furobenzopyran-5-one (prim-O-glucosylcimifugin).Keywords: - Angelica japonica; chromone; coumarin; dihydropyranochromone; dihydrofurochromone; sec-O-glucosylhamaudol; prim-O-glucosylcimifugin
