Check Digit Verification of cas no
The CAS Registry Mumber 2957-90-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,5 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2957-90:
(6*2)+(5*9)+(4*5)+(3*7)+(2*9)+(1*0)=116
116 % 10 = 6
So 2957-90-6 is a valid CAS Registry Number.

REACTION OF DI(BROMOMAGNESIO)ALKANES WITH UNSYMMETRICALLY SUBSTITUTED CYCLIC ANHYDRIDES
Canonne, Persephone,Lemay, Gilles,Belanger, Denis
, p. 4167 - 4170 (1980)
Alkylated γ-spirolactones were prepared in one-step reactions in high yields from butane-1,4-diyl and pentane-1,5 diyldimagnesium dibromides and substituted cyclic anhydrides in tetrahydrofuran.In the light of experimental findings electronic and steric factors influence the regiospecificity of this reaction.
