Check Digit Verification of cas no

The CAS Registry Mumber 1308652-74-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,8,6,5 and 2 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1308652-74:
(9*1)+(8*3)+(7*0)+(6*8)+(5*6)+(4*5)+(3*2)+(2*7)+(1*4)=155
155 % 10 = 5
So 1308652-74-5 is a valid CAS Registry Number.

Highly efficient carbazolyl-derived phosphine ligands: Application to sterically hindered biaryl couplings

Chun To, Sheung,Yee Kwong, Fuk

supporting information; experimental part, p. 5079 - 5081 (2011/06/10)

A new family of phosphine ligands bearing a bulky carbazolyl scaffold is described. With the combination of ligand 2a and Pd(OAc)2, difficult tri-ortho-substituted biaryl couplings are accomplished smoothly. In particular, the catalyst loading as low as 0.02 mol% of Pd for non-activated 2,6-disubstituted aryl chloride coupling can be achieved.
