Check Digit Verification of cas no

The CAS Registry Mumber 76820-35-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,8,2 and 0 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 76820-35:
(7*7)+(6*6)+(5*8)+(4*2)+(3*0)+(2*3)+(1*5)=144
144 % 10 = 4
So 76820-35-4 is a valid CAS Registry Number.

IODINATION PROCESS FOR THE PREPARATION OF 3,5-DISUBSTITUTED-2,4,6-TRIIODO AROMATIC AMINES COMPOUNDS

-

, (2013/05/22)

The invention discloses a improved process for the preparation of 3,5-disubstituted- 2,4,6-triiodo aromatic amines of formula (II), wherein R1 and R2 are defined as herein. The compounds of formula (II) are the key intermediates for the synthesis of a series of non-ionic contrast agents such as Iopamidol, Iohexol and Iodixanol. The process comprises reacting chlorine-free iodinating reagents with 3,5-disubstituted-2,4,6-triiodo aromatic amines to obtain 3,5-disubstituted-2,4,6-triiodo aromatic amines of formula (II), wherein the molar yield of the iodination reaction can reach to 89%.

New brominated compounds as contrast media for X-ray mammography

-

, (2008/06/13)

The invention regards new brominated compounds containing one or two phenyl rings with favorable physico-chemical properties, good tolerance profile, stability and suitable pharmacokinetic profile as contrast media for X-ray mammography, their pharmaceutical formulations and radiological application. The described new bromine contrast media will increase the sensitivity and specificity of X-ray mammography especially in problematic cases. The new contrast media have a higher X-ray absorption than iodine in the energy range used by mammography, a high hydrophilicity, lower toxicity and better tolerance profile than corresponding iodinated compounds.
