Check Digit Verification of cas no

The CAS Registry Mumber 21159-73-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,1,5 and 9 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 21159-73:
(7*2)+(6*1)+(5*1)+(4*5)+(3*9)+(2*7)+(1*3)=89
89 % 10 = 9
So 21159-73-9 is a valid CAS Registry Number.

EVIDENCE FOR ANTI-BOND MIGRATION IN THE PHOTOREARRANGEMENT OF 2-D-EXOBENZONORBORNENYL-2-CHLORIDE

Morrison, Harry,Cardenas, Lourdes M.

, p. 2527 - 2530 (1984)

Photolysis of the title compund to exo-2-benzonorbornenyl methyl ether proceeds with scrambling of the deuterium between C1 and C2, indicative of migration of the anti aryl group.

A convenient route to both enantiomers of endo-2-benzonorbornenol via lipase catalysed resolution of the racemic mixture

Fernandez, Franco,Garcia-Mera, Xerardo,Rodriguez-Borges, Jose Enrique

, p. 365 - 368 (2007/10/03)

Resolution of racemic edo-benzonorbornenol (±)-4 was performed using Candida antarctica lipase (Novozym 435) in benzene (50°C/50 hours) with vinyl acetate as the acyl donor to afford (-)-endo-2-benzonorbornenol (-)-6 and their corresponding (+)-endo-2-ben
