Check Digit Verification of cas no

The CAS Registry Mumber 935658-30-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,5,6,5 and 8 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 935658-30:
(8*9)+(7*3)+(6*5)+(5*6)+(4*5)+(3*8)+(2*3)+(1*0)=203
203 % 10 = 3
So 935658-30-3 is a valid CAS Registry Number.

The first asymmetric total syntheses and determination of absolute configurations of xestodecalactones B and C

Liang, Qiren,Zhang, Jiyong,Quan, Weiguo,Sun, Yongquan,She, Xuegong,Pan, Xinfu

, p. 2694 - 2697 (2007/10/03)

The first efficient asymmetric total syntheses of xestodecalactones B and C have been accomplished in 10 steps with an overall yield of 22 and 20.2%, respectively. The key steps involve the utility of Evans oxazolidinone-mediated syn-aldol condensations to establish the C-9 configuration and the macrolide ring formation by intramolecular acylation. The absolute configurations of xestodecalactones B and C have been determined via these syntheses.
