120626-54-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 120626-54-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,6,2 and 6 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 120626-54:
(8*1)+(7*2)+(6*0)+(5*6)+(4*2)+(3*6)+(2*5)+(1*4)=92
92 % 10 = 2
So 120626-54-2 is a valid CAS Registry Number.

NEIGHBOURING GROUP EFFECTS ON REGIOSELECTIVITY OF WITTIG REACTIONS WITH MALEIC ANHYDRIDES

Kayser, Margaret M.,Breau, Livain

, p. 6203 - 6206 (1988)

Condensations of stabilized Wittig reagent 1 with a variety of substituted maleic anhydrides are discussed.It is proposed that the alkoxy substituents can act as Lewis bases towards the phosphorus of the ylid.Such complexation, stabilizing the transition state for the reaction at the neighbouring carbonyl function, is an important factor in regioselectivity control.
