Check Digit Verification of cas no

The CAS Registry Mumber 1577201-68-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,7,7,2,0 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1577201-68:
(9*1)+(8*5)+(7*7)+(6*7)+(5*2)+(4*0)+(3*1)+(2*6)+(1*8)=173
173 % 10 = 3
So 1577201-68-3 is a valid CAS Registry Number.

Lewis acid catalyzed (3 + 2)-annulations of donor-acceptor cyclopropanes and ynamides

Mackay, William D.,Fistikci, Meryem,Carris, Ryan M.,Johnson, Jeffrey S.

supporting information, p. 1626 - 1629 (2014/04/17)

The Sc(OTf)3-catalyzed (3 + 2)-annulation of donor-acceptor cyclopropanes and ynamides is described, providing the corresponding cyclopentene sulfonamides in good to excellent yield. Deprotection and hydrolysis of the resulting ensulfonamides delivers 2,3-substituted cyclopentanones with high diastereoselectivity.
