1191092-55-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1191092-55-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,1,0,9 and 2 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1191092-55:
(9*1)+(8*1)+(7*9)+(6*1)+(5*0)+(4*9)+(3*2)+(2*5)+(1*5)=143
143 % 10 = 3
So 1191092-55-3 is a valid CAS Registry Number.

Synthesis of (+)-striatene: confirmation of its stereostructure
Brémond, Paul,Vanthuyne, Nicolas,Audran, Gérard
body text, p. 5723 - 5725 (2009/12/09)
The first enantioselective synthesis of natural striatene (+)-1, isolated from liverwort Ptychanthus striatus, starting from commercially available (R)-Pulegone is described. Its stereostructure was confirmed by X-ray analysis of a 3,5-dinitrobenzoate der
