Check Digit Verification of cas no

The CAS Registry Mumber 111097-63-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,0,9 and 7 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 111097-63:
(8*1)+(7*1)+(6*1)+(5*0)+(4*9)+(3*7)+(2*6)+(1*3)=93
93 % 10 = 3
So 111097-63-3 is a valid CAS Registry Number.

DIASTEREOSELECTIVE ALKYLATION OF THE DIANION OF 5-ETHOXY-4(S)-HYDROXY-1-ISOPROPYL-2-PYRROLIDINONE; SHYNTHESIS OF ENANTIOMERICALLY PURE AZABICYCLES

Klaver, Wim J.,Hiemstra, Henk,Speckamp, Nico

, p. 1581 - 1584 (2007/10/02)

The alkylation of the dianion of the title compound (2), readily prepared from (S)-malic acid, with ω-iodo-1-trimethylsilyl-2-alkynes (8a-c) occurs with high trans-selectivity with respect to the hydroxyl function.The products (11a-c) cyclize in formic acid to enantiomerically pure azabicyclic allenes (12a-c), one of which (12b) might be a suitable precursor to peduncularine (15).
