Check Digit Verification of cas no

The CAS Registry Mumber 137038-70-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,0,3 and 8 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 137038-70:
(8*1)+(7*3)+(6*7)+(5*0)+(4*3)+(3*8)+(2*7)+(1*0)=121
121 % 10 = 1
So 137038-70-1 is a valid CAS Registry Number.

Five new napelline-type diterpene alkaloids from Aconitum liangshanium

Takayama,Wu,Eda,Oda,Aimi,Sakai

, p. 1644 - 1646 (2007/10/02)

The structures of five new C20-diterpene alkaloids having the napelline skeleton, i.e., 12-epi-lucidusculine (2), 12-epi-19-dehydronapelline (8), 12-epi-19-dehydrolucidusculine (9), liangshanine (3), and liangshanone (11), found from the roots of Aconitum liangshanium, were determined by spectroscopic analysis and chemical reactions.
