Check Digit Verification of cas no
The CAS Registry Mumber 208338-09-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,8,3,3 and 8 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 208338-09:
(8*2)+(7*0)+(6*8)+(5*3)+(4*3)+(3*8)+(2*0)+(1*9)=124
124 % 10 = 4
So 208338-09-4 is a valid CAS Registry Number.

Synthesis of (3S,3S′,4S,4S′)-1,1′-ethylenedipyrrolidine- 3,3′,4,4′-tetraol and related diamino diols: Donor-acceptor hydrogen-bonding motifs of the C2 symmetric 3,4-dihydroxypyrrolidine unit

Enantiopure 1,1′-ethylenedipyrrolidines possessing 3,4-disubstitution have been prepared from esters of l-(+)-tartaric acid. Although diacylation routes via the diacetoxypyrrolidin-2,5-diones were problematic, N,N-dialkylation protocols proved to be reliable and led to the synthesis of (3S,3S′,4S,4S′)-1,1′-ethylenedipyrrolidine-3,3′,4, 4′-tetraol, (3R,3′S,4R,4′S)-3,4-diamino-1,1′- ethylenedipyrrolidine-3′,4′-diol and (3R,3′R,4S,4′S)-3, 3′-diamino-1,1′-ethylenedipyrrolidine-4,4′-diol. The tetraol possesses a crystal structure that exhibits an unusual zig-zag intermolecular pattern comprising a network of hydrogen bonds involving the terminal hydroxyl groups and a nitrogen atom of one of the pyrrolidine rings.
