Check Digit Verification of cas no

The CAS Registry Mumber 88061-91-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,0,6 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 88061-91:
(7*8)+(6*8)+(5*0)+(4*6)+(3*1)+(2*9)+(1*1)=150
150 % 10 = 0
So 88061-91-0 is a valid CAS Registry Number.

Fused s-Triazino Heterocycles. X. Displacement Reactions of 7,9-Dibromo-2-tribromomethyl-5-trichloromethyl-1,3,4,6,9b-pentaazaphenalene and 7,9-Dibromo-2,5-bis(tribromomethyl)-1,3,4,6,9b-pentaazaphenalene

Shaw, John T.,Starkey, Kenneth D.,Pelliccione, David J.,Barnhart, Sharon L.

, p. 1095 - 1098 (2007/10/02)

The preparation of 7,9-dibromo-2-tribromomethyl-5-trichloromethyl-1,3,4,6,9b-pentaazaphenalene (1c) and 7,9-dibromo-2,5-bis(tribromomethyl)-1,3,4,6,9b-pentaazaphenalene (1d) is described.Reaction of 1c with various nucleophiles cenverted it to the corresponding 7,9-dibromo-2,5-bis-substituted derivatives, the trihalomethyl groups serving as leaving groups.Displacement, first of one tribromomethyl group on 1d by pyrrolidine, and then by various nucleophiles on the remaining tribromomethyl group led to several mixed 2,5-disubstituted derivatives.
