Check Digit Verification of cas no

The CAS Registry Mumber 139003-45-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,0,0 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 139003-45:
(8*1)+(7*3)+(6*9)+(5*0)+(4*0)+(3*3)+(2*4)+(1*5)=105
105 % 10 = 5
So 139003-45-5 is a valid CAS Registry Number.

176. Reaction of the 5-Azoniafulvene Ion with Enamines: A New Approach to Pyrrolizines

Schaerer, Daniel,Jindra, Vladimir,Bringhen, Alain O.,Burger, Ulrich

, p. 1817 - 1822 (2007/10/02)

The synthesis of N,N-dimethyl-N-anilinium chloride (14) and of the corresponding p-toluidinium salt 15 is described.These salts, when dissolved in polar solvents, are shown to be in equilibrium with 1-(chloromethyl)pyrrole (17) and thereby potentially with the 5-azoniafulvene ion (2).Consequently, they react under very mild conditions (MeCN, 60 deg C) with enamines to give pyrrolizine derivatives in acceptable yield (40-50percent).The process is rationalized in terms of an initial Mannich-type reaction which is immediately followed by a cyclization.
