Check Digit Verification of cas no
The CAS Registry Mumber 25767-20-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,7,6 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 25767-20:
(7*2)+(6*5)+(5*7)+(4*6)+(3*7)+(2*2)+(1*0)=128
128 % 10 = 8
So 25767-20-8 is a valid CAS Registry Number.

Studies on the tetramerization of substituted monopyrroles to type I porphyrins
Pichon-Santander,Scott
, p. 6967 - 6969 (2002)
Investigation of the tetramerization of pyrroles bearing two different electron-donating groups as substituents led to the rapid preparation under slightly acidic conditions of a porphyrin analog family with a high ratio of type I isomer for enzymatic act

Syntheses of type-I porphyrins via monopyrrole tetramerization
Nguyen, Liem T.,Smith, Kevin M.
, p. 7177 - 7180 (2007/10/03)
Treatment of 2-[(N,N-dialkylamino)methyl]pyrrole-5-carboxylic acids (e.g. 10,12 or 11,13) in methanol with K3Fe(CN)6 gives type-I porphyrins (etioporphyrin-I 7, coproporphyrin-I tetramethyl ester 16, respectively); with pyrroles 10,12 the product 7 is contaminated with about 8% of other type-isomer(s).
Porphyrin synthesis from nitrocompounds
Ono, Noboru,Kawamura, Hisayuki,Bougauchi, Masahiro,Maruyama, Kazuhiro
, p. 7483 - 7496 (2007/10/02)
A new porphyrin synthesis starting from nitroalkenes or their equivalents is described. For example, octaethylporphyrin, coproporphyrin, porphyrin-1,2,3,4,5,6,7,8 octapropionic acid, and 2,7,12,17 tetraarylporphyrin are prepared in good yield from readily available materials such as 1-nitropropane, nitroethane, nitromethane, and aldehydes.
