Check Digit Verification of cas no
The CAS Registry Mumber 71254-91-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,2,5 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 71254-91:
(7*7)+(6*1)+(5*2)+(4*5)+(3*4)+(2*9)+(1*1)=116
116 % 10 = 6
So 71254-91-6 is a valid CAS Registry Number.

MODELS OF FOLATE COENZYMES-VII SYNTHESIS AND CARBON TRANSFER REACTIONS OF N5,N10-METHENYL AND N5,N10-METHYLENETETRAHYDROFOLATE MODELS

Carboxylate esters react with 1,2-diaminoethanes to yield imidazolines, which upon consecutive reaction with acetic anhydride or tosyl chloride and methyl iodide give imidazolinium salts that serve as models of N5,N10-(CH+)-tetrahydrofolate (THF) coenzymes (7a,b and 18a,b).Reduction of the latter salts with sodium borohydride or reaction with anions (R-) give the corresponding 5,10--THF models.Mono- and bifunctional nucleophiles react with 18a,b to yield carbon-transfer products. 6-Alkylamino-1,3-dimethyluracils react with 1-tosyl-3,4,4-trimethylimidazolidine (the reduction product of 18b), in the presence of acetic acid, to form carbon-transfer products via a mechanism which bears close analogy to the mechanism of action of thymidylate synthetase.
