3771-89-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 3771-89-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,7 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3771-89:
(6*3)+(5*7)+(4*7)+(3*1)+(2*8)+(1*9)=109
109 % 10 = 9
So 3771-89-9 is a valid CAS Registry Number.

DITERPENES FROM LEYSSERA GNAPHALOIDES
Tsichritzis, F.,Jakupovic, J.
, p. 211 - 213 (2007/10/02)
The aerial parts of Leyssera gnaphaloides afforded seven new diterpenes, four labdanes, two 13-epimanoyloxide derivatives as well as one kaur-15-ene derivative.The structures were elucidated by high field NMR spectroscopy.
