660-65-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 660-65-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,6 and 0 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 660-65:
(5*6)+(4*6)+(3*0)+(2*6)+(1*5)=71
71 % 10 = 1
So 660-65-1 is a valid CAS Registry Number.

A new method for the synthesis of carboxylic esters and lactones with di-2-thienyl carbonate (2-DTC) by the promotion of DMAP and iodine

Oohashi, Yoshiaki,Fukumoto, Kentarou,Mukaiyama, Teruaki

, p. 1508 - 1519 (2007/10/03)

The esterification of carboxylic acids with alcohols by using di-2-thienyl carbonate (2-DTC) in the presence of a catalytic amount of 4-(dimethylamino) pyridine (DMAP) proceeded smoothly to afford the corresponding esters in good-to-high yields along with 2(5H)-thiophenone. This esterification was accelerated by the addition of an equimolar amount of iodine to afford the esters in higher yields within a shorter reaction time. Further, cyclization of ω-hydroxycarboxylic acids with an equimolar amount of 2-DTC in the presence of a catalytic amount of DMAP, followed by the addition of 1-4 equimolar amounts of iodine, afforded the corresponding lactones in good-to-high yields under mild conditions. This method was successfully employed in the synthesis of erythro-aleuritic acid lactone.

A new method for the lactonization of ω-hydroxy carboxylic acids with Di-2-thienyl carbonate by the promotion of DMAP and iodine

Oohashi, Yoshiaki,Fukumoto, Kentarou,Mukaiyama, Teruaki

, p. 72 - 73 (2007/10/03)

Successive reactions of ω-hydroxycarboxylic acids with an equimolar amount of di-2-thienyl carbonate (2-DTC) in the presence of a catalytic amount of 4-(dimethylamino)pyridine (DMAP) followed by an addition of 2-4 equimolar amounts of iodine afforded the corresponding lactones in good to high yields.

A new method for the polymer-supported synthesis of cyclic oligoesters for potential applications in macrocyclic lactone synthesis and combinatorial chemistry

Ruddick, Clare L.,Hodge, Philip,Cook, Anthony,McRiner, Andrew J.

, p. 629 - 637 (2007/10/03)

Attachment of ω-hydroxyalkanecarboxylic acids to Merrifield beads followed by treatment with a catalytic amount of di-n-butyltin oxide in chlorobenzene at 133 °C for 4-18 h brought about the formation of the corresponding cyclic oligomers (COs) as the mai
