Check Digit Verification of cas no

The CAS Registry Mumber 1255536-57-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,5,5,3 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1255536-57:
(9*1)+(8*2)+(7*5)+(6*5)+(5*5)+(4*3)+(3*6)+(2*5)+(1*7)=162
162 % 10 = 2
So 1255536-57-2 is a valid CAS Registry Number.

Evaluation of electron-deficient phosphine ligands for direct arylation of heterocycles

Rene, Olivier,Fagnou, Keith

, p. 2116 - 2120 (2010)

New electron-deficient biarylphosphine ligands were studied and proved to be efficient for the direct arylation of heteroarenes with aryl iodides. The ability of a more electron-deficient palladium centre to accelerate the arylation of heterocycles that remained unreactive with aryl iodides in the past has been validated and these heteroarenes can now be smoothly reacted in the presence of a new electrophilic catalyst. Experimental evidence suggests a viable concerted metalation-deprotonation pathway for the C-H bond cleavage step with an electron-deficient palladium centre.
