Check Digit Verification of cas no

The CAS Registry Mumber 128412-94-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,4,1 and 2 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 128412-94:
(8*1)+(7*2)+(6*8)+(5*4)+(4*1)+(3*2)+(2*9)+(1*4)=122
122 % 10 = 2
So 128412-94-2 is a valid CAS Registry Number.

Aqua(sulfato)platinum(II) Complexes with Variable Substituents in the 2-Phenyl Ring. 1. Synthesis and Antitumor and Estrogenic Properties

Gust, Ronald,Burgemeister, Thomas,Mannschreck, Albrecht,Schoenenberger, Helmut

, p. 2535 - 2544 (2007/10/02)

Erythro- and threo-configurated aqua(sulfato)platinum(II) complexes with variable substituents in the 2-phenyl ring (2-PtSO4 to 9-PtSO4: H, 4-F, 3-OH, 4-OH, 2,6-F2, 2,6-Cl2, 2-F/4-OH, 2-Cl/4-OH) were synthesized and tested for estrogenic and antitumor activities.The ligands were obtained by a three-step reaction.The stilbenes were reacted with a mixture of IN3 and NaN3 to yield the respective 1,2-diazido-1,2-diphenylethanes.The subsequent reduction with LiAlH4 led to the corresponding 1,2-diphenylethylenediamines.The (sulfato)platinum(II) complexes were synthesized by reaction of Ag2SO4 with the diiodo complexes, which had been obtained by coordination of the diamines with K2PtI4.Two complexes, erythro-8-PtSO4 and erythro-9-PtSO4, possess antitumor and estrogenic effects and are therefore of interest for the therapy of breast cancer.
