Check Digit Verification of cas no
The CAS Registry Mumber 691007-05-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,1,0,0 and 7 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 691007-05:
(8*6)+(7*9)+(6*1)+(5*0)+(4*0)+(3*7)+(2*0)+(1*5)=143
143 % 10 = 3
So 691007-05-3 is a valid CAS Registry Number.

Process for making risperidone and intermediates therefor

Page/Page column 7, (2008/06/13)
The formation of risperidone is enhanced by the use of enriched Z-isomer oxime intermediate(s) of formula (3) or (7). The oxime(s) can be isomerically enriched by a variety of techniques including the use of the novel acetic acid salt thereof, which affords, inter alia, resolution of the isomers and/or by heat conversion.
