681029-62-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 681029-62-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,1,0,2 and 9 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 681029-62:
(8*6)+(7*8)+(6*1)+(5*0)+(4*2)+(3*9)+(2*6)+(1*2)=159
159 % 10 = 9
So 681029-62-9 is a valid CAS Registry Number.

Asymmetric aldol reactions using catalytic D(+)-proline: A new, economic and practical approach to a commonly employed C1-C6 keto-acid synthon of the epothilones

Zheng, Yansong,Avery, Mitchell A.

, p. 2091 - 2095 (2007/10/03)

A new approach to ketoacid 4, a common C1-C6 fragment used in the total synthesis of epothilones was initiated by direct aldol reaction of acetone with a pivaldehyde-like substance 5, catalyzed with D-proline, leading to a 2,6-diketoalcohol with better than 99% ee. Further intramolecular closure of the diketone 8 followed by oxidation of the silyl protected hydroxycyclohexenone 14 led to the desired product 4. None of the steps have been optimized, yet the overall yield for the four-step process is 31%. The use of commercially available D-proline to construct the chiral center of 4 under very mild reaction conditions provided an economical and practical method for its construction.
