Check Digit Verification of cas no

The CAS Registry Mumber 1290143-97-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,0,1,4 and 3 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1290143-97:
(9*1)+(8*2)+(7*9)+(6*0)+(5*1)+(4*4)+(3*3)+(2*9)+(1*7)=143
143 % 10 = 3
So 1290143-97-3 is a valid CAS Registry Number.

Rhodium-catalyzed enantioselective cyclizations of γ-alkynylaldehydes with acyl phosphonates: ligand- and substituent-controlled C-P or C-H bond cleavage

Masuda, Kengo,Sakiyama, Norifumi,Tanaka, Rie,Noguchi, Keiichi,Tanaka, Ken

, p. 6918 - 6921 (2011)

It has been established that a cationic rhodium(I)/(R)-H8-BINAP or (R)-Segphos complex catalyzes two modes of enantioselective cyclizations of γ-alkynylaldehydes with acyl phosphonates via C-P or C-H bond cleavage. The ligands of the Rh(I) comp
