Check Digit Verification of cas no

The CAS Registry Mumber 303988-75-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,3,9,8 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 303988-75:
(8*3)+(7*0)+(6*3)+(5*9)+(4*8)+(3*8)+(2*7)+(1*5)=162
162 % 10 = 2
So 303988-75-2 is a valid CAS Registry Number.

Synthesis, characterization and reactions of enantiomerically pure 'winged' spirane porphyrazines

Hachiya,Cook,Williams,Montalban,Barrett,Hoffman

, p. 6565 - 6569 (2007/10/03)

A series of enantiomerically pure porphyrazineoctaol derivatives have been prepared from L-(+)-dimethyl tartrate via conversion into the corresponding dispoke protected dihydroxymaleonitrile, Linstead macrocyclization and transmetallation. The derived chloromanganese(III) complexes catalyzed the epoxidation of styrene with sodium hypochlorite as the oxygen atom source but with modest enantioselectivities (25%).
