Check Digit Verification of cas no
The CAS Registry Mumber 1834-01-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,3 and 4 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1834-01:
(6*1)+(5*8)+(4*3)+(3*4)+(2*0)+(1*1)=71
71 % 10 = 1
So 1834-01-1 is a valid CAS Registry Number.

Stereocontrolled synthesis of the C21-C38 fragment of the unnatural enantiomer of the antibiotic nystatin A1.
Berkenbusch, Thilo,Brueckner, Reinhard
, p. 1545 - 1557 (2007/10/03)
The C(21)-C(38) fragment all-trans-41 of the unnatural enantiomer 1 of nystatin A(1) was prepared starting from the N-propionyl oxazolidinone 9. Aldol adduct ent-8 (ee > 96 %) derived in two steps was hydroborated with (thexyl)BH(2). Oxidative work-up and treatment with acid furnished delta-lactone 4. It contains the complete stereotetrade of the target molecule. The alpha,beta-unsaturated ester 28 was reached after another four steps. It should be a precursor for the polyene moieties of a variety of polyol,polyene macrolides. Illustrating that, the alpha,beta-unsaturated aldehyde 29 obtained from 28 and DIBAL was extended by 10 C atoms in four steps yielding the C(21)-C(38) segment 41. The latter set of transformations included the regio- and stereoselective Claisen rearrangement 32-->35.
