The CAS Registry Mumber 91323-04-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,3,2 and 3 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 91323-04:
(7*9)+(6*1)+(5*3)+(4*2)+(3*3)+(2*0)+(1*4)=105
105 % 10 = 5
So 91323-04-5 is a valid CAS Registry Number.

Chlorination of N-Tritylproline Methyl Ester

Polyak, F. D.,Eremeev, A. V.,Gavars, M. P.,Gaukhman, A. P.,Mazheika, I. B.

, p. 733 - 735 (1988)

The reaction of N-tritylproline methyl ester with tert-butyl hypochlorite gave 2,4-dichloro-2-methoxycarbonyl-5-pyrroline, which is readily converted to 2-methoxycarbonyl-4-chloropyrrole.The intermediate products were identified by chromatographic mass spectrometry when the reaction was carried out at low temperatures.
