Check Digit Verification of cas no

The CAS Registry Mumber 6650-29-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,5 and 0 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6650-29:
(6*6)+(5*6)+(4*5)+(3*0)+(2*2)+(1*9)=99
99 % 10 = 9
So 6650-29-9 is a valid CAS Registry Number.

Synthesis of haptens and conjugates for ELISAs of phytoestrogens. Development of the immunological tests

Bennetau-Pelissero, Catherine,Le Houerou, Cyril,Lamothe, Valerie,Le Menn, Francoise,Babin, Pierre,Bennetau, Bernard

, p. 305 - 311 (2000)

Seven carboxylic acid haptens of isoflavonoids were synthesized, with the spacer arm on the oxygen atom at the C7 position for one series, with formononetin, daidzein, equol, biochanin A, and genistein, and at the C8 position for a second series, with only formononetin and daidzein. The different haptens were coupled to bovine serum albumin (BSA) and to swine thyroglobulin (Thyr). Polyclonal antibodies were generated against the BSA conjugates. Enzyme-linked immunosorbent assays (ELISAs) were developed based on competition between free phytoestrogens and the Thyr-hapten conjugates for specific antibodies. IC50 values of the standard curves ranged between 0.8 and 20 ng/mL that is, 0.3 and 9.2 pmol/well. The antibodies obtained should be useful for assays in vegetable matter as well as in biological fluids after a separation step. These ELISAs should be valuable also in the food industry to control phytoestrogen concentrations prior to and after processing.
