Check Digit Verification of cas no

The CAS Registry Mumber 259670-59-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,9,6,7 and 0 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 259670-59:
(8*2)+(7*5)+(6*9)+(5*6)+(4*7)+(3*0)+(2*5)+(1*9)=182
182 % 10 = 2
So 259670-59-2 is a valid CAS Registry Number.

Application of oxidative desymmetrization of meso-tetrahydrofurans: Syntheses of functionalized chiral building blocks and of (-)-alloyohimbane

Miyafuji, Akio,Ito, Katsuji,Katsuki, Tsutomu

, p. 261 - 272 (2007/10/03)

Oxidative desymmetrization of oxygen functionalized mesotetrahydrofurans was successfully achieved (up to 87% ee) through (salen)manganese(III) catalyzed enantiotopic selective C-H oxidation. The enantioselective synthesis of (-)-alloyohimbane (12) has also been achieved in a short step by using oxidative desymmetrization of meso-tetrahydrofuran as the key step.
