Check Digit Verification of cas no

The CAS Registry Mumber 231944-87-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,1,9,4 and 4 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 231944-87:
(8*2)+(7*3)+(6*1)+(5*9)+(4*4)+(3*4)+(2*8)+(1*7)=139
139 % 10 = 9
So 231944-87-9 is a valid CAS Registry Number.

Chiral syntheses of 2,3,5-trisubstituted pyrrolidines by silicon-directed cyclization of allylsilanes bearing a sulfonamide moiety

Akiyama, Takahiko,Ishida, Yuhsuke,Kagoshima, Hirotaka

, p. 4219 - 4222 (1999)

Bronsted acid-catalyzed cyclization of chiral N-tosyl-3-silyl-4-pentenamine proceeded smoothly by way of a β-silyl carbocation intermediate to furnish 2,3,5-trisubstituted pyrrolidines in enantiomerically pure form.
