Check Digit Verification of cas no

The CAS Registry Mumber 143037-77-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,0,3 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 143037-77:
(8*1)+(7*4)+(6*3)+(5*0)+(4*3)+(3*7)+(2*7)+(1*7)=108
108 % 10 = 8
So 143037-77-8 is a valid CAS Registry Number.

Selective Mono- and Polymethylene Homologations of Copper Reagents Using (Iodomethyl)zinc Iodide

Sidduri, AchyuthaRao,Rozema, Michael J.,Knochel, Paul

, p. 2694 - 2713 (2007/10/02)

A wide range of unsaturated aryl-, alkenyl-, alkynylcopper compounds can be selectively homologated by a methylene unit using (iodomethyl)zinc iodide or bis(iodomethyl)zinc.These reactions allow the generation of mixed allylic zinc-copper compounds which can be efficiently trapped with carbonyl compounds.An application to a general preparation of functionalized α-methylene-γ-butyrolactones is described.The homologation of alkynylcoppers with (iodomethyl)zinc iodide allows a one-pot preparation of propargylic copper reagents which in the presence of a carbonyl compound provide various homopropargylic alcohols in excellent yields.In the absence of an electrophile, a clean quadruple methylene homologation of alkynylcoppers occurs to furnish dienic copper reagents.The homologation of other types of copper reagents is also possible, and carbanions at the α-position to amines as well as homoenolates of aldehydes or ketones can also be prepared by this method.
