Check Digit Verification of cas no

The CAS Registry Mumber 82414-34-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,4,1 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 82414-34:
(7*8)+(6*2)+(5*4)+(4*1)+(3*4)+(2*3)+(1*4)=114
114 % 10 = 4
So 82414-34-4 is a valid CAS Registry Number.

SELECTIVITY IN CYCLOADDITIONS-IX CYCLOADDITIONS OF NITRILE OXIDES TO INDOLES. REACTIVITY AND REGIOCHEMISTRY

Caramella, P,Corsico, A. Coda,Corsaro, A,Del Monte, D.,Albini, F. Marinone

, p. 173 - 182 (2007/10/02)

Cycloadditions of benzonitrile oxide and mesitonitrile oxide to N-methylindole and indole yield the acid sensitive cycloadducts 1 a-d with high regioselectivity.With N-carbethoxyindole the stable cycloadducts 1 e,f and minor amounts of the regioisomeric 2 e,f are isolated.The electron withdrawing substituent reduces both the regioselectivity and the reactivity of the cycloadditions.Frontier orbital considerations, based on MINDO/3 calculations, allow elucidation of the observed changes in reactivity and regiochemistry.
