Check Digit Verification of cas no
The CAS Registry Mumber 205240-90-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,2,4 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 205240-90:
(8*2)+(7*0)+(6*5)+(5*2)+(4*4)+(3*0)+(2*9)+(1*0)=90
90 % 10 = 0
So 205240-90-0 is a valid CAS Registry Number.

Enantiocontrolled synthesis of the functionalized cis-decalin
Ozaki, Miki,Omodani, Tomoki,Bando, Toshikazu,Shishido, Kozo
, p. 81 - 84 (2007/10/03)
An enantioselective synthesis of the functionalized cis-decalin (2) has been accomplished employing a highly diastereoselective intramolecular [3+2] dipolar cycloaddition reaction of the optically active nitrile oxide (16) as the key step.
