Check Digit Verification of cas no

The CAS Registry Mumber 16580-19-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,5,8 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 16580-19:
(7*1)+(6*6)+(5*5)+(4*8)+(3*0)+(2*1)+(1*9)=111
111 % 10 = 1
So 16580-19-1 is a valid CAS Registry Number.

Organocalcium Chemistry: Preparation and Reactions of Highly Reactive Calcium

Wu, Tse-Chong,Xiong, Heping,Rieke, R. D.

, p. 5045 - 5051 (2007/10/02)

A highly reactive form of calcium was prepared by the reduction of Ca(II) salts with preformed lithium biphenylide.Remarkably, this activated calcium undergoes oxidative addition to organic bromides, chlorides, or even fluorides to form the organocalcium reagents under very mild conditions in high yields.The resulting organocalcium compounds undergo Grignard-type reactions.Transmetalation with Cu(I) salts forms calcium cuprate reagents which undergo a variety of cross-coupling reactions.The activated calcium reacts with 1,3-dienes to yield the corresponding 2-butene-1,4-diylcalcium complexes.These bis-organocalcium reagents can undergo dialkylation reactions with α,ω-alkylene dihalides and dichlorosilanes to form the corresponding 3-, 5-, and 6-membered ring derivatives.Significantly, these reactions are highly stereospecific and regioselective.
