330470-11-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 330470-11-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,0,4,7 and 0 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 330470-11:
(8*3)+(7*3)+(6*0)+(5*4)+(4*7)+(3*0)+(2*1)+(1*1)=96
96 % 10 = 6
So 330470-11-6 is a valid CAS Registry Number.

Synthesis of spirocycles via ring closing metathesis of heterocycles carrying gem-diallyl substituents obtained via ring opening of (halomethyl)cyclopropanes with allyltributyltin

Gurjar, Mukund K.,Ravindranadh, Somu V.,Sankar, Kuppusamy,Karmakar, Sukhen,Cherian, Joseph,Chorghade, Mukund S.

, p. 1366 - 1373 (2007/10/03)

In the presence of allyl tri-n-butyltin-AlBN, cyclopropylmethyl bromides/xanthates undergo ring-opening reaction with concomitant formation of geminal diallyl derivatives in good yields. The ring closing metathesis reactions on geminal diallyl derivatives with Grubbs' catalyst provided spirocyclopentenyl products. Combination of these two methodologies has been applied to the synthesis of mono-, bis-cyclopentyl-carbohydrates as well as spirocyclopentylproline derivatives.

Mild and efficient methodology for installation of gem-diallyl functionality on carbohydrate synthons

Gurjar,Ravindranadh,Karmakar

, p. 241 - 242 (2007/10/03)

A versatile approach to construct gem-diallyl functionality has been described.
