Check Digit Verification of cas no

The CAS Registry Mumber 640283-73-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,0,2,8 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 640283-73:
(8*6)+(7*4)+(6*0)+(5*2)+(4*8)+(3*3)+(2*7)+(1*3)=144
144 % 10 = 4
So 640283-73-4 is a valid CAS Registry Number.

A Combinatorial Synthesis of a Macrosphelide Library Utilizing a Palladium-Catalyzed Carbonylation on a Polymer Support

Takahashi, Takashi,Kusaka, Shin-Ichi,Doi, Takayuki,Sunazuka, Toshiaki,Omura, Satoshi

, p. 5230 - 5234 (2003)

Supported total synthesis: The combinatorial synthesis of a 122-membered macrosphelide library including macrosphelides A, C, E, and F (see picture) has been achieved based on a unique strategy for a three-component coupling utilizing a palladium-catalyzed chemoselective carbonylation and an unprecedented macrolactonization on a polymer support.

Stereoselective synthesis of macrosphelide i

Veena, Bacchu,Sharma, Gangavaram V. M.

, p. 2039 - 2043 (2014/11/08)

An efficient total synthesis of macrosphelide I, has been achieved starting from commercially available chiral materials, ethyl (S)-lactate and methyl (R)-3-hydroxybutyrate. Titanium(IV) promoted the regioselective nucleophilic opening reaction of epoxy a
