124901-16-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 124901-16-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,9,0 and 1 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 124901-16:
(8*1)+(7*2)+(6*4)+(5*9)+(4*0)+(3*1)+(2*1)+(1*6)=102
102 % 10 = 2
So 124901-16-2 is a valid CAS Registry Number.

A New Synthesis of Porphyrins via Tetramerization of 2-(Hydroxymethyl)pyrroles
Ono, Noboru,Maruyama, Kazuhiro
, p. 1237 - 1240 (2007/10/02)
Acid catalyzed cyclization of 2-(hydroxymethyl)pyrroles with electron-donating substituents at the β-position gives a mixture of four isomers of porphyrins (type I-IV) in the homogeneous reaction.The isomerization during cyclization can be minimized in th
