Check Digit Verification of cas no

The CAS Registry Mumber 33237-87-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,2,3 and 7 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 33237-87:
(7*3)+(6*3)+(5*2)+(4*3)+(3*7)+(2*8)+(1*7)=105
105 % 10 = 5
So 33237-87-5 is a valid CAS Registry Number.

Nucleophilic Substitution Reactions of Indan-2-yl Arenesulfonates with Anilines in Methanol

Lee, Ikchoon,Lee, Young Sook,Huh, Chul,Lee, Hai Whang,Lee, Byung Choon

, p. 2415 - 2418 (1993)

The nucleophilic substitution reactions of (Y)-indan-2-yl (Z)-arenesulfonates with (X)-anilines in methanol at 55.0 deg C are reported.Sign reversals in all three second-order cross-interaction constants, ρXY, ρYZ and ρXZ, are observed at non-interaction points Z = -0.11 (ρXY = 0), X = -0.02 (ρYZ = 0) and Y = 0.43 (ρXZ = 0) respectively, which have been ascribed to an unusually large third-order cross-interaction constant, ρXYZ = -0.53, for the reaction series.An SN2 transition state with a tilted, parallel stacked and displaced structure of the three benzene rings in the nucleophile (X), substrate (Y) and leaving group (Z) is proposed to rationalize the strong three-body coupling manifested by the large ρXYZ value.
