61826-31-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 61826-31-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,8,2 and 6 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 61826-31:
(7*6)+(6*1)+(5*8)+(4*2)+(3*6)+(2*3)+(1*1)=121
121 % 10 = 1
So 61826-31-1 is a valid CAS Registry Number.

Synthesis of (-)-(S, S)-clemastine by invertive N → C aryl migration in a lithiated carbamate

Fournier, Anne M.,Brown, Robert A.,Farnaby, William,Miyatake-Ondozabal, Hideki,Clayden, Jonathan

supporting information; experimental part, p. 2222 - 2225 (2010/08/04)

The first enantioselective synthesis of the antihistamine agent clemastine, as its (S,S)-stereoisomer, has been achieved by ether formation between a proline-derived chloroethylpyrrolidine and an enantiomerically enriched tertiary alcohol. The tertiary alcohol was formed from the carbamate derivative of α-methyl-p-chlorobenzyl alcohol by invertive aryl migration on lithiation. The (S,S)-stereochemistry of the product confirms the invertive nature of the rearrangement.
