Check Digit Verification of cas no

The CAS Registry Mumber 174623-94-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,6,2 and 3 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 174623-94:
(8*1)+(7*7)+(6*4)+(5*6)+(4*2)+(3*3)+(2*9)+(1*4)=150
150 % 10 = 0
So 174623-94-0 is a valid CAS Registry Number.

A highly stereoselective formal synthesis of hapalosin

Kumar, Harish,Reddy, A. Srinivas,Yadav,Reddy, B. V. Subba

, p. 1415 - 1419 (2013/07/26)

A flexible and highly diastereoselective formal synthesis of hapalosin, a cyclodepsipeptide isolated from the blue green alga Hapalosiphon welwitschii and having multidrug-resistance-reversing activity is described. The synthetic route involves the addition of organometallic reagent to N-tert- butanesulfinylimine, Jung nonaldol aldol reaction, and Yamaguchi esterification as key steps.

Synthesis and evaluation of hapalosin and analogs as MDR-reversing agents

O'Connell, Celeste E.,Salvato, Kathleen A.,Meng, Zhaoyang,Littlefield, Bruce A.,Schwartz, C. Eric

, p. 1541 - 1546 (2007/10/03)

The marine natural product hapalosin and 22 analogs, which incorporated systematic substituent deletions or variations, were prepared. These compounds were evaluated in a cell-based assay for both MDR-reversing activity and general cytotoxicity. Some substituent modifications resulted in lower cytotoxicities, but most structural changes were either detrimental to or did not seriously alter the MDR-reversing activity.
