103305-32-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 103305-32-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,3,0 and 5 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 103305-32:
(8*1)+(7*0)+(6*3)+(5*3)+(4*0)+(3*5)+(2*3)+(1*2)=64
64 % 10 = 4
So 103305-32-4 is a valid CAS Registry Number.

Acyclic Stereoselection in the Ortho Ester Claisen Rearrangement

Daub, G. William,Edwards, James P.,Okada, Carol R.,Allen, Jana Westran,Maxey, Claudia Tata,Wells, Matthew S.,Goldstein, Alexandra S.,Dibley, Michael J.,Wang, Clarence J.,Ostercamp, Daniel P.,Chung, Steven,Cunningham, Paula Shanklin,Berliner, Martin A.

, p. 1976 - 1985 (2007/10/03)

The ortho ester Claisen rearrangement of trisubstituted allylic alcohols exhibits significant levels of diastereoselection. In E allylic alcohols, a 1,3-diaxial interaction develops in the chairlike transition state leading to the anti isomer, rendering the reaction syn selective by a factor of 3-5 to 1. In Z allylic alcohols, the 1,3-diaxial interaction develops in the transition state leading to the syn isomer, generating an anti:syn selectivity of 6-15 to 1. The relative stereochemistry of the syn isomer was confirmed independently by the synthesis of the mycotoxin botryodiplodin.

Stereoselective Acid-Catalyzed Claisen Rearrangements

Daub, William G.,Shanklin, Paula L.,Tata, Claudia

, p. 3402 - 3405 (2007/10/02)

An alkyl substituent in the 2-position of an E trisubstituted allylic alcohol confers significant diastereoselectivity on ortho ester and ketal Claisen rearrangements of the system.
