Check Digit Verification of cas no

The CAS Registry Mumber 188647-58-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,6,4 and 7 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 188647-58:
(8*1)+(7*8)+(6*8)+(5*6)+(4*4)+(3*7)+(2*5)+(1*8)=197
197 % 10 = 7
So 188647-58-7 is a valid CAS Registry Number.

Stereoselective Total Synthesis of the Diastereomeric Tricyclic Alkaloids Tetraponerine-7 and Tetraponerine-8 Using O-Pivaloylated d -Arabinopyranosylamine as the Common Auxiliary

Strassnig, Irina,K?rber, Karsten,Hünger, Udo,Kunz, Horst

, p. 2299 - 2316 (2015)

Based on a diastereoselective domino Mannich-Michael reaction cascade of 2-N-[(S)-3-{(benzyloxycarbonyl)[4-(tert-butyldiphenylsiloxy)butyl]amino}octylidene]-2,3,4-tri-O-pivaloyl-α-d-arabinopyranosylamine with the Danishefsky diene, the major component of

Vinylogous urethanes in alkaloid synthesis. Applications to the synthesis of racemic indolizidine 209B and its (5A*,8S*,8aS*)-(±) diastereomer, and to (-)-indolizidine 209B

Michael, Joseph P.,Gravestock, David

, p. 1919 - 1928 (2007/10/03)

Syntheses of racemic (5A*,8S*,8aS*)-8-methyl-5-pentylindolizidine (indolizidine 209B) (±)-l and its hitherto unknown ((5A*,8S*,8aS*) diastereomer (±)-20 were accomplished in eight steps from pyrrolidine-2-thione and ethyl oct-2-enoate. Key steps included
