Check Digit Verification of cas no

The CAS Registry Mumber 1240326-75-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,3,2 and 6 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1240326-75:
(9*1)+(8*2)+(7*4)+(6*0)+(5*3)+(4*2)+(3*6)+(2*7)+(1*5)=113
113 % 10 = 3
So 1240326-75-3 is a valid CAS Registry Number.

Asymmetric synthesis of erythro-8-O-4'-neolignan Machilin C

Xia, Yamu,Chang, Liang,Ding, Yining,Jiao, Bin

, p. 151 - 152 (2011/07/08)

A new methodology for the synthesis of the erythro-8-O-4'-neolignan Machilin C based on the Sharpless asymmetric dihydroxylation reaction and the Mitsunobu reaction as two key steps is described.

Asymmetric synthesis of machilin C and its analogue

Xia, Yamu,Wang, Wei

, p. 630 - 636 (2011/10/19)

Full details of the asymmetric total synthesis of erythro-8-O-4′-neolignan, machilin C, and its analogue perseal A are reported. The synthesis was involved in the Sharpless dihydroxylation reaction that occurred with excellent asymmetric induction, and the Mitsunobu reaction which occurred with inversion of the absolute configuration from the threo to the erythro isomer. The synthesis was achieved from simple vanillin in eight to twelve steps.

Asymmetric synthesis of 8-O-4′-neolignan perseal B

Xia, Ya-Mu,Wang, Wei,Guo, Ying-Lan,Li, Jun-Feng

experimental part, p. 375 - 380 (2010/11/03)

Full details of an enantioselective total synthesis of 8-O-4'-neolignan perseal B are presented for the first time. The synthesis was achieved in 8 steps from vanillin and involved the asymmetric dihydroxylation reaction using AD-mix-α to give the key intermedium (1S,2S)-1-(4-(benzyloxy)-3- methoxyphenyl)propane-1,2,3-triol, and the Mitsunobu reaction between phenylpropanoid and vanillin formed perseal B. The synthetic method of perseal B exhibits a new route for 8-O-4'-neolignan. TUBITAK.
