Check Digit Verification of cas no

The CAS Registry Mumber 21906-04-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,0 and 6 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 21906-04:
(7*2)+(6*1)+(5*9)+(4*0)+(3*6)+(2*0)+(1*4)=87
87 % 10 = 7
So 21906-04-7 is a valid CAS Registry Number.

Arenediazonium o-benzenedisulfonimides in Heck-type arylation of allylic alcohols

Barbero, Margherita,Cadamuro, Silvano,Dughera, Stefano

, p. 3443 - 3452 (2006)

Arenediazonium o-benzenedisulfonimides were reacted with primary and secondary allylic alcohols. The reactions, carried out in aqueous ethanol in the presence of palladium(II) acetate as precatalyst and sodium hydrogen carbonate as base, gave the arylation products with good overall conversion. In all cases, the major products were the β-arylated carbonyl derivatives. The o-benzene-disulfonimide was recovered in high yield from all the reactions, and it was recycled for the preparation of other salts. Georg Thieme Verlag Stuttgart.
