Check Digit Verification of cas no
The CAS Registry Mumber 67546-50-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,5,4 and 6 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 67546-50:
(7*6)+(6*7)+(5*5)+(4*4)+(3*6)+(2*5)+(1*0)=153
153 % 10 = 3
So 67546-50-3 is a valid CAS Registry Number.

PROCESS FOR THE PREPARATION OF OPTICALLY ACTIVE (4E)-5- HALO-2-ALKYLPENT-4-ENOIC ACIDS AND THEIR ESTER DERIVATIVES
-
Page/Page column 27, (2008/06/13)
A process for the preparation of optically active (4E)-5-halo-2-alkylpent-4-enoic acids and their ester derivatives by a stereoselective synthesis which employs camphorsultam as chiral auxiliary is disclosed; in particular methyl (2S, 4E)-5-chloro-2-isopropylpent-4-enoate is prepared, which is a key intermediate in the manufacturing of the new anti-hypertension drug Aliskiren. Furthermore novel N-(5-halo-2-alkylpent-4-enoyl) camphorsultams are provided. A process for the hydrolysis of substituted N-acylcamphorsultams with strong acids is also provided.
