Check Digit Verification of cas no

The CAS Registry Mumber 68930-68-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,9,3 and 0 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 68930-68:
(7*6)+(6*8)+(5*9)+(4*3)+(3*0)+(2*6)+(1*8)=167
167 % 10 = 7
So 68930-68-7 is a valid CAS Registry Number.

A diastereoselective oxa-pictet-spengler-based strategy for (+)-frenolicin B and epi -(+)-frenolicin B synthesis

Zhang, Yinan,Wang, Xiachang,Sunkara, Manjula,Ye, Qing,Ponomereva, Larissa V.,She, Qing-Bai,Morris, Andrew J.,Thorson, Jon S.

, p. 5566 - 5569 (2013)

An efficient diastereoselective oxa-Pictet-Spengler reaction strategy was developed to construct benzoisochroman diastereomers. The utility of the reaction was demonstrated in the context of both the total synthesis of naturally occurring pyranonaphthoquinones (+)-frenolicin B and epi-(+)-frenolicin B as well as a range of frenolicin precursor analogs. The method is versatile and offers exquisite stereocontrol and, as such, offers a synthetic advance for the synthesis of pyranonaphthoquinone analogs.

A chiron approach to the total synthesis of (-)-juglomycin A, (+)-kalafungin, (+)-frenolicin B, and (+)-deoxyfrenolicin

Fernandes, Rodney A.,Chavan, Vijay P.,Mulay, Sandip V.,Manchoju, Amarender

, p. 10455 - 10460 (2013/01/15)

A general, efficient, and common strategy for the synthesis of (-)-juglomycin A, (+)-kalafungin, (+)-frenolicin B, and (+)-deoxyfrenolicin is reported here. The strategy involves the synthesis of a key building block alkyne from a cheap chiral pool material, d-glucono-δ-lactone, Doetz benzannulation, oxa-Pictet-Spengler reaction, and H2SO 4-mediated epimerization.

Direct Total Syntheses of Frenolicin B and Kalafungin via Highly Regioselective Diels-Alder Reactions

Kraus, George A.,Li, Jun,Gordon, Mark S.,Jensen, Jan H.

, p. 1154 - 1159 (2007/10/02)

Frenolicin B, an anticoccidial agent, has been synthesizes in six steps from ketone 3.Racemic kalafungin, an antifungal agent, has been synthesized in five steps.The key step in both syntheses, a regioselective Diels-Alder reaction, proceeds with complete
