Check Digit Verification of cas no

The CAS Registry Mumber 1516900-23-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,1,6,9,0 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1516900-23:
(9*1)+(8*5)+(7*1)+(6*6)+(5*9)+(4*0)+(3*0)+(2*2)+(1*3)=144
144 % 10 = 4
So 1516900-23-4 is a valid CAS Registry Number.

Biotinylated metathesis catalysts: Synthesis and performance in ring closing metathesis

Kajetanowicz, Anna,Chatterjee, Anamitra,Reuter, Raphael,Ward, Thomas R.

, p. 373 - 379 (2014/06/24)

Nine biotinylated Grubbs-Hoveyda and Grubbs-type metathesis catalysts were synthesized and evaluated in ring closing metathesis reactions of N-tosyl diallylamine and 5-hydroxy-2-vinylphenyl acrylate. Their catalytic activity in organic-and aqueous solvents was compared with the second generation Grubbs-Hoveyda catalyst. The position of the biotin-moiety on the N-heterocyclic carbene was found to critically influence the catalytic activity of the corresponding ruthenium-based catalysts.
