25163-50-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 25163-50-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,1,6 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 25163-50:
(7*2)+(6*5)+(5*1)+(4*6)+(3*3)+(2*5)+(1*0)=92
92 % 10 = 2
So 25163-50-2 is a valid CAS Registry Number.

Total synthesis of the terpenoid buddledone A: 11-membered ring-closing metathesis

Cai, Zhengxin,Yongpruksa, Nattawut,Harmata, Michael

, p. 1661 - 1663 (2012/07/01)

The first total synthesis of buddledone A was accomplished in seven steps from methyl ethyl ketone (MEK). The key step in the sequence featured an 11-membered ring formation by ring-closing metathesis.

Total syntheses of epothilones B and D

Jung, Jae-Chul,Kache, Rajashaker,Vines, Kimberly K.,Zheng, Yan-Song,Bijoy, Panicker,Valluri, Muralikrishna,Avery, Mitchell A.

, p. 9269 - 9284 (2007/10/03)

A convergent, total synthesis of epothilones B (2) and D (4) is described. The key steps are Normant coupling to establish the desired (Z)-stereochemistry at C12-C13, Wadsworth-Emmons olefination of methyl ketone 28 with the phosphonate ester 8, diastereoselective aldol condensation of aldehyde 5 with the enolate of keto acid derivatives to form the C6-C7 bond, selective deprotection of acid 52, and macrolactonization.
