Check Digit Verification of cas no

The CAS Registry Mumber 1101850-30-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,0,1,8,5 and 0 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1101850-30:
(9*1)+(8*1)+(7*0)+(6*1)+(5*8)+(4*5)+(3*0)+(2*3)+(1*0)=89
89 % 10 = 9
So 1101850-30-9 is a valid CAS Registry Number.

Kinetic resolution of β-alkenyl-, β-alkynyl- and β-flavenyl-substituted β-hydroxy esters in asymmetric dehydration

Min, Hee Lee,Eui, Ta Choi,Kim, Dajung,Yoon, Min Lee,Yong, Sun Park

experimental part, p. 5630 - 5637 (2009/05/27)

Catalytic asymmetric dehydration of β-alkenyl- or alkynyl-substituted β-hydroxy esters by kinetic resolution has been investigated with five different chiral ligands 3-7. The kinetic resolution of a variety of racemic β-hydroxy tert-butyl esters in the presence of a prolinol chiral ligand and BrZnCH2CO2tBu provided highly enantio-enriched β-hydroxy esters 9-22 with selectivity factors ranging from 11 to 59. In addition, the application of this asymmetric synthetic methodology to the preparation of enantio-enriched flavene derivatives 23-29 is demonstrated. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.
