Check Digit Verification of cas no

The CAS Registry Mumber 1138156-56-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,8,1,5 and 6 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1138156-56:
(9*1)+(8*1)+(7*3)+(6*8)+(5*1)+(4*5)+(3*6)+(2*5)+(1*6)=145
145 % 10 = 5
So 1138156-56-5 is a valid CAS Registry Number.

Practical imidazole-based phosphine ligands for selective palladium-catalyzed hydroxylation of aryl halides

Schulz, Thomas,Torborg, Christian,Schaeffner, Benjamin,Huang, Jun,Zapf, Alexander,Kadyrov, Renat,Boerner, Armin,Beller, Matthias

supporting information; experimental part, p. 918 - 921 (2009/05/15)

(Chemical Equation Presented) The phenol countdown: Novel imidazole-based phosphine ligands are synthesized on scales up to 100 g by a convenient lithiation-phosphorylation method. The phosphines are stable towards air and moisture and are successfully applied as ligands in the palladium-catalyzed selective hydroxylation of aryl halides (see scheme, dba=dibenzylideneacetone).
