Check Digit Verification of cas no

The CAS Registry Mumber 166272-10-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,6,2,7 and 2 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 166272-10:
(8*1)+(7*6)+(6*6)+(5*2)+(4*7)+(3*2)+(2*1)+(1*0)=132
132 % 10 = 2
So 166272-10-2 is a valid CAS Registry Number.

Reactions of Cyclic Oxalyl Compounds, 37. - Substituent Effects on the Site of Nucleophilic Attack at 1H-Pyrrole-2,3-diones

Kappe, C. Oliver,Terpetschnig, Ewald,Penn, Gerhard,Kollenz, Gert,Peters, Karl,et al.

, p. 537 - 544 (2007/10/02)

Reactions of 1H-pyrrole-2,3-diones 2a-i with N- and O-nucleophiles proceed by initial attack at C-2 or/and C-5.Consequently, earlier results suggesting structures of type A (attack at C-3) have to be revised (5, 13, 17, 18b).In general, electron-withdrawi
