Check Digit Verification of cas no

The CAS Registry Mumber 2652-77-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,5 and 2 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2652-77:
(6*2)+(5*6)+(4*5)+(3*2)+(2*7)+(1*7)=89
89 % 10 = 9
So 2652-77-9 is a valid CAS Registry Number.

Exocyclic delocalization at the expense of aromaticity in 3,5-bis(π-donor) substituted pyrazolium ions and corresponding cyclic bent allenes

Fernandez, Israel,Dyker, C. Adam,DeHope, Alan,Donnadieu, Bruno,Frenking, Gernot,Bertrand, Guy

, p. 11875 - 11881 (2009)

Small ring allenes are usually highly strained and highly reactive species, and for a long time considered only as transient intermediates. The recent isolation of a five membered heterocyclic allene 1f has raised questions and debate regarding the factor

Chiral Pincer Carbodicarbene Ligands for Enantioselective Rhodium-Catalyzed Hydroarylation of Terminal and Internal 1,3-Dienes with Indoles

Marcum, Justin S.,Roberts, Courtney C.,Manan, Rajith S.,Cervarich, Tia N.,Meek, Simon J.

supporting information, p. 15580 - 15583 (2017/11/14)

Catalytic enantioselective addition of N-heteroarenes to terminal and internal 1,3-dienes is reported. Reactions are promoted by 5 mol % of Rh catalyst supported by a new chiral pincer carbodicarbene ligand that delivers allylic substituted arenes in up to 95% yield and up to 98:2 er. Mechanistic and X-ray evidence is presented that supports that the reaction proceeds via a Rh(III)-η3-allyl.
