Check Digit Verification of cas no

The CAS Registry Mumber 1026561-39-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,6,5,6 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1026561-39:
(9*1)+(8*0)+(7*2)+(6*6)+(5*5)+(4*6)+(3*1)+(2*3)+(1*9)=126
126 % 10 = 6
So 1026561-39-6 is a valid CAS Registry Number.

Hydroxylated pyrrolidines. Enantiospecific synthesis of all-cis 2,3,4,5-substituted pyrrolidine derivatives from serine

Verma, Sharad K.,Atanes, M. Nieves,Busto, J. Hector,Thai, Dung L.,Rapoport, Henry

, p. 1314 - 1318 (2007/10/03)

We report the enantiospecific synthesis of the sterically congested all-cis 2,3,4,5-substituted pyrrolidines 4, 5, and 6, from either D- or L-serine. Hemiaminal intermediate 13 is converted to the fully substituted pyrrolidine 15 by way of a tandem Wittig-Michael reaction. The endo stereochemistry of the C-3 methyl group of compound 15 is set by stereoselective reduction of the double bond in 11, driven by a preference for hydrogenation from the rear side of the molecule. The all-cis configuration of these fully substituted pyrrolidines has been established by X-ray analysis of compound 6. Removal of the benzenesulfonyl group from the highly substituted and functionalized intermediate 15 is successfully accomplished by sodium naphthalenide reduction.
