The CAS Registry Mumber 848607-48-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,8,6,0 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 848607-48:
(8*8)+(7*4)+(6*8)+(5*6)+(4*0)+(3*7)+(2*4)+(1*8)=207
207 % 10 = 7
So 848607-48-7 is a valid CAS Registry Number.

Cross-coupling of 1-aryl-5-bromopyrazoles: Regioselective synthesis of 3,5-disubstituted 1-arylpyrazoles

Wang, Xiao-Jun,Tan, Jonathan,Grozinger, Karl

, p. 4713 - 4716 (2000)

The cross-coupling of 1-aryl-5-bromopyrazoles 4 with alkynes, vinyltins and arylboronic acids promoted by Pd(PPh3)4 afforded unsymmetrical 3,5- disubstituted 1-arylpyrazoles 5-8 in excellent yields, 1-Aryl-5- bromopyrazoles 4 were prepared from their corresponding 1-arylpyrazolones 3 with PBr3 in refluxing acetonitrile.
