Check Digit Verification of cas no

The CAS Registry Mumber 139255-87-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,5 and 5 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 139255-87:
(8*1)+(7*3)+(6*9)+(5*2)+(4*5)+(3*5)+(2*8)+(1*7)=151
151 % 10 = 1
So 139255-87-1 is a valid CAS Registry Number.

High diastereofacial selectivity in the 1,3-dipolar cycloaddition of chiral azomethine ylides

Deprez,Royer,Husson

, p. 1189 - 1192 (1991)

Excellent diastereofacial and endo/exo stereoselectivities have been obtained in cycloaddition of the chiral azomethine ylide generated from 4-phenyloxazolidine acetic acid (-)-8-phenylmenthyl ester 1e.
