Check Digit Verification of cas no

The CAS Registry Mumber 1233843-43-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,3,8,4 and 3 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1233843-43:
(9*1)+(8*2)+(7*3)+(6*3)+(5*8)+(4*4)+(3*3)+(2*4)+(1*3)=140
140 % 10 = 0
So 1233843-43-0 is a valid CAS Registry Number.

Syntheses of carbocyclic aminonucleosides and (-)-epi-4′-carbocyclic puromycin: application of palladium(0)/indium iodide-allylations and tethered aminohydroxylations

Cesario, Cara,Tardibono Jr., Lawrence P.,Miller, Marvin J.

, p. 3053 - 3056 (2010)

Carbocyclic aminonucleosides and epi-4′-carbocyclic puromycin were prepared from an acylnitroso-derived hetero Diels-Alder cycloadduct. Pd(0)/InI-mediated allylations of a formyl species were used to install the 4′-hydroxymethyl group. A tethered aminohydroxylation strategy was employed to install the cis-2′,3′-aminoalcohol moiety with complete regio- and diastereocontrol.
