Check Digit Verification of cas no

The CAS Registry Mumber 21918-38-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,1 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 21918-38:
(7*2)+(6*1)+(5*9)+(4*1)+(3*8)+(2*3)+(1*8)=107
107 % 10 = 7
So 21918-38-7 is a valid CAS Registry Number.

IRON PENTACARBONYL MEDIATED COUPLING OF BENZYL HALIDES TO KETONES UNDER MILD PHASE TRANSFER CONDITIONS.

Tanguy, Guy,Weinberger, Bernd,Abbayes, Hevre des

, p. 5529 - 5532 (1984)

In a two-phase system (saturated aqueous calcium hydroxide, tetrabutylammonium sulfate, dichloromethane, iron pentacarbonyl) benzyl bromides are readily carbonylated to dibenzyl ketones ; α-α' dibromoorthoxylene yields the o-quinodimethane iron tricarbonyl cmplex 8.It is inferred that the reactions proceed through transient generation of the tetracarbonyl ferrate dianion.
