Check Digit Verification of cas no

The CAS Registry Mumber 1167430-59-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,7,4,3 and 0 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1167430-59:
(9*1)+(8*1)+(7*6)+(6*7)+(5*4)+(4*3)+(3*0)+(2*5)+(1*9)=152
152 % 10 = 2
So 1167430-59-2 is a valid CAS Registry Number.

Facile synthesis of 1-aryl-2,3-dihydro-1H-isoindoles by cyclization of N-formyliminium ion via geometrically disfavored 5-ENDO-trig process

scheme or table, p. 1177 - 1181 (2009/11/30)

Synthesis of l-aryl-2,3-dihydro-1H-isoindoles (isoindolines) (10) was achieved in a highly effective manner via acid catalyzed cyclization of N-foimyliminium ion (8) obtained from 2,3-dimethoxybenzylamine and carbonyl compounds with acetic-formic anhydride under a one pot procedure. This Pictet-Spengler type reaction provides a convenient method for preparing 1-arylisoindolines.
