Check Digit Verification of cas no

The CAS Registry Mumber 98586-58-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,5,8 and 6 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 98586-58:
(7*9)+(6*8)+(5*5)+(4*8)+(3*6)+(2*5)+(1*8)=204
204 % 10 = 4
So 98586-58-4 is a valid CAS Registry Number.

Reactions at the β-carbon of anionic tungsten acetylide complexes: Ion pairing, vinylidene formation, and CO2 binding

Birdwhistell,Templeton

, p. 2062 - 2064 (2008/10/08)

Addition of CO2 to the β-carbon of Li[fac(OC)3(dppe)WC≡CR] (R = Me, n -Bu) followed by methylation yields vinylidene products, mer-(OC)3(dppe)W= C=C(R)CO2Me. Ion-pair formation at the β-carbon may act as a kinetic mediator in this system. We also report syntheses of mer-(OC)3(dppe)W=C=CRR′ complexes, including the parent C=CH2 derivative.
