Check Digit Verification of cas no

The CAS Registry Mumber 141983-21-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,9,8 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 141983-21:
(8*1)+(7*4)+(6*1)+(5*9)+(4*8)+(3*3)+(2*2)+(1*1)=133
133 % 10 = 3
So 141983-21-3 is a valid CAS Registry Number.

Studies on Selective Nucleophilic Substitution Reactions of + PF6- Complexes (M = Fe, Ru)

Pearson, Anthony J.,Park, Jewn G.,Zhu, Ping Y.

, p. 3583 - 3589 (2007/10/02)

Reactions of + PF6- complexes (M = Fe, Ru) with phenoxide nucleophiles were found to proceed with excellent selectivity under mild conditions to give products of monosubstitution.Using aminophenoxides, a preference for O-arylation was observed, while amino alcohols such as prolinol react selectively on nitrogen.Methodology for sequential selective displacement of both chlorides by different nucleophiles is reported.
