Check Digit Verification of cas no

The CAS Registry Mumber 2874-94-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,7 and 4 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2874-94:
(6*2)+(5*8)+(4*7)+(3*4)+(2*9)+(1*4)=114
114 % 10 = 4
So 2874-94-4 is a valid CAS Registry Number.

Preparation, reactivities, and NMR spectra of pentafluorophenyltin derivatives

Chen, Jian-Xie,Sakamoto, Katsumasa,Orita, Akihiro,Otera, Junzo

, p. 58 - 65 (2007/10/03)

A variety of pentafluorophenyltin compounds were prepared and their chemical properties were examined. These compounds effectively catalyzed Mukaiyama-aldol reaction of ketene silyl acetal in sharp contrast to the inertness of normal alkyltin halides like Bu2SnCl2. The increased Lewis acidity of the pentafluorophenyltin halides was proved by 119Sn- and 13C-NMR spectra. On the other hand, the pentafluorophenyl group reduced the reactivities of tin towards both nucleophiles and electrophiles. 19F-NMR spectroscopy was invoked to elucidate this anomaly.
