Check Digit Verification of cas no

The CAS Registry Mumber 105126-40-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,1,2 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 105126-40:
(8*1)+(7*0)+(6*5)+(5*1)+(4*2)+(3*6)+(2*4)+(1*0)=77
77 % 10 = 7
So 105126-40-7 is a valid CAS Registry Number.

Immunomodulatory agents: Dioxothiadiazabicyclo[3.3.0]octanes and their 2- spiro derivatives

Refouvelet,Harraga,Nicod,Robert,Seilles,Couquelet,Tronche

, p. 1076 - 1083 (2007/10/02)

A series of 6,8-dioxo-3-thia-1,7-diazabicyclo[3.3.0]octanes and a series of 6,8-dioxo-3-thia-1,7-diazabicyclo[3.3.0]octane 2-spiro derivatives were synthesized from L-(-)-R-cysteine ethyl ester in two steps. The synthetic route involved condensation of the amino acid with an appropriate aldehyde or ketone, then a further condensation of the resultant ethyl thiazolidine-4- carboxylate with an isocyanate or an isothiocyanate. The proliferative response to human lymphocyte mitogen (phytohemagglutinin) was used as a primary screening assay for most of the thiadiazabicyclic compounds in comparison with levamisole. Furthermore, the most active compounds were tested for ability to release soluble receptors (sRIL-2) after mitogenic stimulation of T cells and for ability to activate macrophage oxidative metabolism measured by chemiluminescence. Most compounds were active in all three tests and some showed dose-dependent activity.
