Check Digit Verification of cas no

The CAS Registry Mumber 68409-21-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,4,0 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 68409-21:
(7*6)+(6*8)+(5*4)+(4*0)+(3*9)+(2*2)+(1*1)=142
142 % 10 = 2
So 68409-21-2 is a valid CAS Registry Number.

Regioselective Addition of Grignard Reagents to 3-Methoxy- and 3-Nitrophthalic Anhydride

Braun, Manfred,Veith, Reiner,Moll, Gerard

, p. 1058 - 1070 (2007/10/02)

The regioselectivity in the addition of the grignard reagents 5a and 6a to the anhydrides 1 and 2 is determined by the solvent system: in a highly selective manner (3:97), the meta carbonyl group is attacked in tetrahydrofuran/tetramethylethylenediamine, while predominant, but relatively unselective (maximum 78:22) addition to the ortho carbonyl group is observed in diethyl ether.The influence of the solvent system on the regioselectivity is discussed.The LUMO-coefficients of the carbonyl carbon atoms in 1 and 2 were calculated.
