107856-75-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 107856-75-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,8,5 and 6 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 107856-75:
(8*1)+(7*0)+(6*7)+(5*8)+(4*5)+(3*6)+(2*7)+(1*5)=147
147 % 10 = 7
So 107856-75-7 is a valid CAS Registry Number.

Tobacco chemistry. 65. Two new 7,8-epoxycembranoids from tobacco.
Wahlberg,Eklund,Vogt,Enzell,Berg
, p. 855 - 860 (2007/10/02)
Two new diterpenoids have been isolated from tobacco. They have been identified as the (1S,2E,4S,6R,7R,8R,11E)- and (1S,2E,4S,6R,7S,8S,11E)-7,8-epoxy-2,11-cembradiene-4,6-diols 1 and 2 by synthesis and X-ray analysis. The conformation about the 5,6 bond in some 7,8-epoxycembranoids is discussed, as is the biogenesis of the two new compounds.
