128140-96-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128140-96-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,1,4 and 0 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 128140-96:
(8*1)+(7*2)+(6*8)+(5*1)+(4*4)+(3*0)+(2*9)+(1*6)=115
115 % 10 = 5
So 128140-96-5 is a valid CAS Registry Number.

CONVENIENT SYNTHESIS OF VARIOUS TERHETEROCYCLIC COMPOUNDS BY Pd(O)-CATALYZED COUPLING REACTIONS
Gronowitz, Salo,Peters, Dan
, p. 645 - 658 (2007/10/02)
Various terheterocyclic compounds containing thiophene, furan, selenophene, pyridine and thiazole rings have been obtained by the Pd(PPh3)4-catalyzed coupling of dihalo-substituted heterocyclic compounds with heterocyclic boronic acids, using sodium bicar
