Check Digit Verification of cas no

The CAS Registry Mumber 815610-23-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,1,5,6,1 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 815610-23:
(8*8)+(7*1)+(6*5)+(5*6)+(4*1)+(3*0)+(2*2)+(1*3)=142
142 % 10 = 2
So 815610-23-2 is a valid CAS Registry Number.

Efficient synthesis of the azabicyclo[3.3.1]nonane ring system in the alkaloid methyllycaconitine using bis(alkoxymethyl)alkylamines as aminoalkylating agents in a double Mannich reaction

Brimble, Margaret A.,Brocke, Constanze

, p. 2385 - 2396 (2007/10/03)

The double Mannich reaction of cyclic β-keto esters with bis-(alkoxymethyl)alkylamines provides an efficient and versatile method for the construction of azabicyclo[3.3.1]nonanes and azabicyclo[3.2.1]octanes. The optimum conditions for efficient reaction involve use of the activator trichloromethylsilane in acetonitrile as solvent at ambient temperature. The utility of this synthetic method is further demonstrated by the facile synthesis of several AE ring analogues 39, 42 of the alkaloid methyllycaconitine by appendage of the key N-(methylsuccininimido)anthranilate pharmacophore to the N-(3-phenylpropyl)-substituted double Mannich adducts 18, 27.
