Check Digit Verification of cas no

The CAS Registry Mumber 1049706-69-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,9,7,0 and 6 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1049706-69:
(9*1)+(8*0)+(7*4)+(6*9)+(5*7)+(4*0)+(3*6)+(2*6)+(1*9)=165
165 % 10 = 5
So 1049706-69-5 is a valid CAS Registry Number.

Ortho-(Dimesitylboryl)phenylphosphines: Positive boryl effect in the palladium-catalyzed suzuki-miyaura coupling of 2-chloropyridines

, p. 2274 - 2284 (2013/10/01)

Catalytic systems combining ortho-(dimesitylboryl) phenylphosphines and palladium precursors have been evaluated in the Suzuki-Miyaura couplings of chloro-N-heterocycles, in particular 2-chloro pyridines, with arylboronic acids. The Lewis basic character of the substrates does not interfere with the Lewis acidic site of the ligands, even for a substrate featuring free NH2 groups. The influence of several reaction parameters has been studied and the ortho-dimesitylboryl moiety was actually found to substantially enhance the catalytic performance. The role of this group has been examined using preformed phosphine-borane/Pd complexes and the formation of an original phosphine/h4-boratabutadiene complex has been identified as a possible deactivation pathway. Regioselective coupling of 2,6-dichloro-3-nitropyridine with phosphine-borane/Pd catalysts has also been explored, and sequential double cross-couplings were found to give a direct and efficient access to unsymmetrical 2,6-diarylpyridines.
