Check Digit Verification of cas no

The CAS Registry Mumber 927819-93-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,7,8,1 and 9 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 927819-93:
(8*9)+(7*2)+(6*7)+(5*8)+(4*1)+(3*9)+(2*9)+(1*3)=220
220 % 10 = 0
So 927819-93-0 is a valid CAS Registry Number.

PROCESS FOR PRODUCTION OF ARALKYLOXYPYRROLIDINE DERIVATIVE

-

Page/Page column 17, (2008/12/07)

The present invention provides a process for producing a 3-aralkyloxypyrrolidine derivative which is important for production of pharmaceutical products and the like. In the present invention, a N-protected-3-hydroxypyrrolidine is converted into a N-protected-3-aralkyloxypyrrolidine by allowing an aralkyl halide to act in the presence of a base and at least one of a metal halide and a phase-transfer catalyst followed by deprotecting a N-protecting group to convert it to a 3-aralkyloxypyrrolidine derivative and subsequently treating the derivative in a solvent containing a polar solvent, thereby obtaining the 3-aralkyloxypyrrolidine derivative as a crystal. According to the present invention, a 3-aralkyloxypyrrolidine derivative of high purity can be produced conveniently and efficiently on an industrial scale.
