Check Digit Verification of cas no

The CAS Registry Mumber 118621-12-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,6,2 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 118621-12:
(8*1)+(7*1)+(6*8)+(5*6)+(4*2)+(3*1)+(2*1)+(1*2)=108
108 % 10 = 8
So 118621-12-8 is a valid CAS Registry Number.

Stereoelectronic Suppresion and a Remarkably Low Effective Concentration for a Cyclization to a Benzo-fused Five-membered Ring

King, James F.,Lam, Joe Y. L.,Skonieczny, Stanislaw

, p. 147 - 148 (2007/10/02)

The cyclization of o-chloromethylbenzylamine to dihydroisoindole has an effective concentration of 8.3 M (in CD3OD at 21 deg C); this very low value for a cyclization to a benzo-fused five-membered ring is ascribed to lessend conjugation in the transition state as compared to that of the model reaction, and is relevant to both the synthesis of rings and the application of effective concentrations in obtaining evidence of mechanism.
