Check Digit Verification of cas no
The CAS Registry Mumber 339308-53-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,9,3,0 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 339308-53:
(8*3)+(7*3)+(6*9)+(5*3)+(4*0)+(3*8)+(2*5)+(1*3)=151
151 % 10 = 1
So 339308-53-1 is a valid CAS Registry Number.

Treatment of (+)-pentacyclo[5.4.0.02,6.03,10.05,9] undecane-8-one with sodium cyanide and ammonium carbonate produced an optically active hydantoin of which the 4′-carbonyl group of the hydantoin ring is in the less sterically hindered equatorial position. Hydrolysis of the latter with barium hydroxide produced (-)-8-amino-pentacyclo [5.4.0.02,6.03,10.05,9]undecane-8-carboxylic acid which has the 1S,2R,3R,5R,6R,7S,8R,9R,10R configuration. In a similar way, (+)-6-amino-tetracyclo-[6.2.0.04,11.05,9] undec-2-ene-6-carboxylic acid with 1R,4R,5R,6R,8S,9S,11R configuration was obtained from (-)-tetracyclo[6.3.0.04,11.05,9]undec-2-ene-6-one. The latter was obtained from (-)-11-hydroxy-pentacyclo [5.4.0.02,6.03,10.05,9]undecan-8-one.
