Check Digit Verification of cas no

The CAS Registry Mumber 1228009-72-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,0,0 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1228009-72:
(9*1)+(8*2)+(7*2)+(6*8)+(5*0)+(4*0)+(3*9)+(2*7)+(1*2)=130
130 % 10 = 0
So 1228009-72-0 is a valid CAS Registry Number.

Rational exploration of N-Heterocyclic carbene (NHC) palladacycle diversity: A highly active and versatile precatalyst for suzuki-miyaura coupling reactions of deactivated aryl and alkyl substrates

Peh, Guang-Rong,Kantchev, Eric Assen B.,Er, Jun-Cheng,Ying, Jackie Y.

supporting information; experimental part, p. 4010 - 4017 (2010/08/05)

As less attention has been focussed on the design of highly efficient palladium precatalysts to ensure the smooth formation of the active catalyst for metal-mediated cross coupling reactions, we herein demonstrate that combining the bulky N-heterocyclic carbene (NHC) 1,3-bis(2,6-diisopropylphenyl)imidazol-2- ylidene (IPr) with cyclopalladated acetanilide as the optimal palladium precatalyst leads to superior catalytic activity compared with the state-of-the-art NHC-Pd catalysts. The complex was discovered through the evaluation of a small, rationally designed library of NHC-palladacycles prepared by a novel, practical and atom-economic method, the direct reaction of IPrHCl with palladacycle acetate dimers.
