Check Digit Verification of cas no

The CAS Registry Mumber 87630-15-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,6,3 and 0 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 87630-15:
(7*8)+(6*7)+(5*6)+(4*3)+(3*0)+(2*1)+(1*5)=147
147 % 10 = 7
So 87630-15-7 is a valid CAS Registry Number.

Stereoselective Cross-Coupling of Grignard Reagents and Conjugated Dienylbromides using Iron Salts with Magnesium Alkoxides

Chourreu, Pablo,Guerret, Olivier,Guillonneau, Lo?c,Gayon, Eric,Lefèvre, Guillaume

, p. 4701 - 4706 (2021)

A convenient procedure allowing iron-catalyzed cross-coupling of alkyl or aryl Grignard reagents and conjugated dienyl bromides is reported, relying on the use of cheap and non-toxic magnesium alkoxides as sole additives. An excellent stereoselectivity is observed in the alkyl-dienyl series. This sequence has been applied to the synthesis of the sex pheromone of codling moth, illustrating its applicability for obtaining targets of industrial interest. Preliminary mechanistic studies carried out on the aryl-dienyl cross-coupling suggest that in situ generated ate homoleptic organoiron(II) species act as catalytically relevant intermediates. A modified preparative method for the realization of THF solutions of dienyl bromides as “ready-to-use” coupling partners is also discussed, circumventing the thermal instability of those derivatives.
