634603-66-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 634603-66-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,4,6,0 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 634603-66:
(8*6)+(7*3)+(6*4)+(5*6)+(4*0)+(3*3)+(2*6)+(1*6)=150
150 % 10 = 0
So 634603-66-0 is a valid CAS Registry Number.

Routes to sydnone-containing oligomeric areneynes
Weisner, Andrew J.,Cooper, Thomas M.,Turnbull, Kenneth
, p. 639 - 651 (2007/10/03)
Iterative Sonogashira-coupling routes have been used to prepare sydnone-containing areneynes 1-3 (and related compounds) from ?-iodophenylsydnone (4). The best results were obtained by using two- and three-reaction-in-one-pot protocols.
