Check Digit Verification of cas no

The CAS Registry Mumber 202392-39-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,2,3,9 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 202392-39:
(8*2)+(7*0)+(6*2)+(5*3)+(4*9)+(3*2)+(2*3)+(1*9)=100
100 % 10 = 0
So 202392-39-0 is a valid CAS Registry Number.

Synthetic study on gymnodimine: Highly stereoselective construction of substituted tetrahydrofuran and cyclohexene moieties

Ishihara, Jun,Miyakawa, Jun,Tsujimoto, Takashi,Murai, Akio

, p. 1417 - 1419 (2007/10/03)

The synthetic studies on gymnodimine, a shellfish toxin, are described. This marine toxin consists of 16-membered carbocycle, tetrahydrofuran, and spiro-imine moieties. Our synthetic strategy involves the stereoselective allylation of tetrahydrofuran compound and the exo-selective intramolecular Diels-Alder reaction.
