Check Digit Verification of cas no
The CAS Registry Mumber 52340-48-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,3,4 and 0 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 52340-48:
(7*5)+(6*2)+(5*3)+(4*4)+(3*0)+(2*4)+(1*8)=94
94 % 10 = 4
So 52340-48-4 is a valid CAS Registry Number.

Pyrrole-singlet oxygen reactions leading to α,α'-bipyrroles. Synthesis of prodigiosin and analogs
Wasserman, Harry H.,Petersen, Anders K.,Xia, Mingde,Wang, Jianji
, p. 7587 - 7589 (1999)
Reaction of the tert-butyl ester of 3-methoxy-2-pyrrolecarboxylic acid with singlet oxygen yields a hydroperoxide intermediate which undergoes coupling with pyrroles to yield precursors of prodigiosin and ring A analogs, readily convertible to the corresponding tripyrromethenes.
