Check Digit Verification of cas no

The CAS Registry Mumber 84691-55-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,6,9 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 84691-55:
(7*8)+(6*4)+(5*6)+(4*9)+(3*1)+(2*5)+(1*5)=164
164 % 10 = 4
So 84691-55-4 is a valid CAS Registry Number.

On the Mechanism of the Nucleophilic Addition to 2,3-Dihydrodipyrrin-1(10H)-ones

Grubmayr, Karl,Wagner, Ulrike Gabriella

, p. 793 - 812 (1988)

1H NMR-spectroscopic investigations of the acid catalyzed addition of methanol to dihydrodipyrrinones (Z)-2, (E)-2, and 4 show the C-protonation of their enamide parts to be the first and rate determining step forming the key intermediate, the N-acyl-immo
