Check Digit Verification of cas no

The CAS Registry Mumber 1429043-31-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,9,0,4 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1429043-31:
(9*1)+(8*4)+(7*2)+(6*9)+(5*0)+(4*4)+(3*3)+(2*3)+(1*1)=141
141 % 10 = 1
So 1429043-31-1 is a valid CAS Registry Number.

Stepwise deprotonation of a thiol-functionalized bis(1,2,4-triazolium) salt as a selective route to heterometallic NHC complexes

Seitz, Stefanie C.,Rominger, Frank,Straub, Bernd F.

, p. 2427 - 2434 (2013)

Heterometallic NHC complexes have been selectively prepared at room temperature directly from an azolium salt in a two-step procedure. In the unsymmetrically substituted bis(1,2,4-triazolium) ligand precursor, one of the m-xylylene-bridged triazolium units features an unprotected o-thiophenol substituent. This renders possible a selective deprotonation and in situ monopalladation at the NHC-thiolato unit. The obtained palladium(II) complex possesses two pendant triazolium units as vacant binding sites. After a second deprotonation/metalation step, a heterodinuclear palladium(II) gold(I) complex and a heterotrinuclear palladium(II) dicopper(I) complex were obtained. In the latter, two metal centers are connected via a thiolato bridge.
