Check Digit Verification of cas no

The CAS Registry Mumber 280565-80-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,0,5,6 and 5 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 280565-80:
(8*2)+(7*8)+(6*0)+(5*5)+(4*6)+(3*5)+(2*8)+(1*0)=152
152 % 10 = 2
So 280565-80-2 is a valid CAS Registry Number.

A practical procedure for the resolution of (+)- and (-)-tramadol

Itov, Zinovy,Meckler, Harold

, p. 291 - 294 (2000)

A practical procedure for the efficient resolution of cis-tramadol [cis-2-(dimethylaminomethyl)-1-(3-methoxyphenyl)cyclohexanol] has been developed. This process was based on the observation that cis-tramadol free base selectively formed mandelic acid salts at different rates, affording a readily scalable kinetic resolution of each enantiomer. The key to the process was the observation that the resolving salt needed to be broken and re-formed to ultimately improve the optical purity. The mandalate salt of each cis-enantiomer was found to be > 99% optically pure after three cycles through the salt formation process. A sample of each mandelate salt enantiomer was successfully converted to the known, optically active hydrochloride salt.
