141054-33-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141054-33-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,0,5 and 4 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 141054-33:
(8*1)+(7*4)+(6*1)+(5*0)+(4*5)+(3*4)+(2*3)+(1*3)=83
83 % 10 = 3
So 141054-33-3 is a valid CAS Registry Number.

Stable isoporphyrin chromophores: Synthesis
Xie, Hong,Smith, Kevin M.
, p. 1197 - 1200 (2007/10/02)
Condensation of a 5,5-disubstituted-dipyrromethanes (6a, 6b) with a 1,9-diformyl-pyrromethane (7) under MacDonald conditions in the presence of zinc(II) acetate affords zinc(II) salts (8a, 8b) possessing the isoporphyrin chromophore, which is stable with
