Check Digit Verification of cas no
The CAS Registry Mumber 71208-55-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,2,0 and 8 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 71208-55:
(7*7)+(6*1)+(5*2)+(4*0)+(3*8)+(2*5)+(1*5)=104
104 % 10 = 4
So 71208-55-4 is a valid CAS Registry Number.

, p. 1681 - 1688 (2007/10/03)
The isolation and identification of an unknown process related impurity in a key intermediate of Rimadyl (carprofen) is described. The structure of the unknown was evaluated by NMR spectral analysis and eventually confirmed by single crystal X-Ray. A re-slurry in warm acetic acid was found to reduce the level of the unknown to an acceptable level.
