Check Digit Verification of cas no

The CAS Registry Mumber 142439-86-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,4,3 and 9 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 142439-86:
(8*1)+(7*4)+(6*2)+(5*4)+(4*3)+(3*9)+(2*8)+(1*6)=129
129 % 10 = 9
So 142439-86-9 is a valid CAS Registry Number.

Highly Selective Synthesis of Halomon, Plocamenone, and Isoplocamenone

Bucher, Cyril,Deans, Richard M.,Burns, Noah Z.

, p. 12784 - 12787 (2015/10/28)

Over 160 chiral vicinal bromochlorinated natural products have been identified; however, a lack of synthetic methods for the selective incorporation of halogens into organic molecules has hindered their synthesis. Here we disclose the first total synthesis and structural confirmation of isoplocamenone and plocamenone, as well as the first selective and scalable synthesis of the preclinical anticancer natural product halomon. The synthesis of these inter-halogenated compounds has been enabled by our recently developed chemo-, regio-, and enantioselective dihalogenation reaction.
