154581-85-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 154581-85-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,5,8 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 154581-85:
(8*1)+(7*5)+(6*4)+(5*5)+(4*8)+(3*1)+(2*8)+(1*5)=148
148 % 10 = 8
So 154581-85-8 is a valid CAS Registry Number.

A NOVEL PHOTOCHEMICAL SYNTHESIS OF PYRROLES FROM β-KETOVINYLOGOUS AMIDES
Winkler, Jeffrey D.,Siegel, Miles G.
, p. 7697 - 7700 (1993)
Irradiation of β-ketovinylogous amides leads to the formation of 3-acylpyrroles.A mechanistic rationale is offered which involves the recombination of a photochemically generated biradical, followed by transannular condensation to give the observed pyrrole product.
