Check Digit Verification of cas no

The CAS Registry Mumber 134836-78-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,8,3 and 6 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 134836-78:
(8*1)+(7*3)+(6*4)+(5*8)+(4*3)+(3*6)+(2*7)+(1*8)=145
145 % 10 = 5
So 134836-78-5 is a valid CAS Registry Number.

Dialkylamino cyclopentadienyl ruthenium(II) complex-catalyzed α-alkylation of arylacetonitriles with primary alcohols

Cheung, Hung Wai,Li, Juan,Zheng, Wenxu,Zhou, Zhongyuan,Chiu, Yu Hin,Lin, Zhenyang,Lau, Chak Po

, p. 265 - 274 (2010)

Aminocyclopentadienyl ruthenium complexes, [(η5-C 5H4NMe2)Ru(PPh3)2(CH 3CN)]+BF4- and [(η5- C5H4NEt2)Ru(PPh3) 2(CH3CN)]+BF4-, are moderately active catalysts for α-alkylation of arylacetonitriles with primary alcohols; on the other hand, the analogous unsubstituted cyclopentadienyl ruthenium complex [(η5-C5H 5)Ru(PPh3)2(CH3CN)] +BF4- shows very low catalytic activity. On the basis of experimental results and theoretical calculations, rationalization for the much higher catalytic activity of the aminocyclopentadienyl complexes over that of the unsubstituted Cp complex is provided. In the catalytic systems with the former, it is possible to regenerate the active solvento complexes via protonation of the metal hydride intermediates and subsequent ligand substitution; this process is, however, very nonfacile in the catalytic system with the latter.
