Check Digit Verification of cas no

The CAS Registry Mumber 2453-58-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,5 and 3 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2453-58:
(6*2)+(5*4)+(4*5)+(3*3)+(2*5)+(1*8)=79
79 % 10 = 9
So 2453-58-9 is a valid CAS Registry Number.

A concise synthesis of (S)-(+)-1-(4-{2-[bis-(4-fluorophenyl)methoxy]-ethyl} piperazin-1-yl)-2-phenylpropan-2-ol dimaleate

Prisinzano, Thomas,Hsin, Ling-Wei,Folk, John E.,Flippen-Anderson, Judith L.,George, Clifford,Jacobson, Arthur E.,Rice, Kenner C.

, p. 3285 - 3289 (2007/10/03)

(S)-(+)-1-(4-{2-[Bis-(4-fluorophenyl)methoxy]-ethyl}piperazin-1-yl) -2-phenylpropan-2-ol dimaleate was prepared in several steps from (S)-(+)-atrolactic acid by a process permitting synthesis of multigram quantities. With the information provided by asymmetric synthesis, the X-ray crystal structure was solved.
