Check Digit Verification of cas no

The CAS Registry Mumber 308822-37-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,8,8,2 and 2 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 308822-37:
(8*3)+(7*0)+(6*8)+(5*8)+(4*2)+(3*2)+(2*3)+(1*7)=139
139 % 10 = 9
So 308822-37-9 is a valid CAS Registry Number.

Synthesis of 2,3-disubstituted pyrroles and pyridines from 3-halo-1-azaallylic anions

Aelterman,De Kimpe,Tyvorskii,Kulinkovich

, p. 53 - 58 (2001)

A new synthesis of 2,3-disubstituted pyrroles and pyridines is described. The reaction of 3-halo-1-azaallylic carbanions, regiospecifically generated from α-halogenated ketimines, with ω-iodoazides led to the regiospecific formation of ω-azido-α-haloketimines. Treatment of these functionalized imines with tin(II) chloride afforded halogenated five- and six-membered cyclic imines, which were transformed under mild conditions into 2,3-disubstituted pyrroles and pyridines. The stereoselective reduction of 2,3-dialkyl-3-chloro-1-pyrrolines to afford cis-2,3-dialkyl-3-chloropyrrolidines is also reported.
