Check Digit Verification of cas no

The CAS Registry Mumber 142940-70-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,9,4 and 0 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 142940-70:
(8*1)+(7*4)+(6*2)+(5*9)+(4*4)+(3*0)+(2*7)+(1*0)=123
123 % 10 = 3
So 142940-70-3 is a valid CAS Registry Number.

Asymmetric hydroformylation of vinyl acetate by use of chiral bis(triarylphosphite) - Rhodium(I) complexes

Sakai,Nozaki,Mashima,Takaya

, p. 583 - 586 (1992)

Bis(triarylphosphite) ligands 1-4 were prepared in optically pure forms from (R)- or (S)-binaphthol and (ArO)2Pcl, and their Rh(I) complexes have been used as catalysts for hydroformylation of vinyl acetate. The corresponding branched aldehyde,
