Check Digit Verification of cas no
The CAS Registry Mumber 750638-97-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,5,0,6,3 and 8 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 750638-97:
(8*7)+(7*5)+(6*0)+(5*6)+(4*3)+(3*8)+(2*9)+(1*7)=182
182 % 10 = 2
So 750638-97-2 is a valid CAS Registry Number.

Preparation of functionalized 3,4-pyridynes via 2-magnesiated diaryl sulfonates
Lin, Wenwei,Chen, Ling,Knochel, Paul
, p. 2787 - 2797 (2007/10/03)
The preparation of functionalized 3,4-pyridynes of type 1 as highly reactive intermediates has been achieved by the controlled elimination of readily generated 2-magnesiated diaryl sulfonates of type 2 obtained by a low temperature I/Mg- or Br/Mg-exchange starting from the corresponding halides of type 3. After trapping with furan, moderate to good yields of the desired functionalized cycloadducts of type 4 are obtained. The addition of a magnesium arylthiolate or magnesium phenylselenide to 3,4-pyridyne followed by quenching with an electrophile is also described.
