145243-92-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 145243-92-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,2,4 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 145243-92:
(8*1)+(7*4)+(6*5)+(5*2)+(4*4)+(3*3)+(2*9)+(1*2)=121
121 % 10 = 1
So 145243-92-1 is a valid CAS Registry Number.

Rapid access to pyrazolo[3,4-c]pyridines via alkyne annulation: Limitations of steric control in nickel-catalyzed alkyne insertions
Heller, Stephen T.,Natarajan, Swaminathan R.
, p. 4947 - 4950 (2007)
Polyfunctionalized pyrazolo[3,4-c]pyridines were readily prepared by the annulation of alkynes with tert-butyl 4-iodopyrazolocarboximines. The reaction was found to be catalyzed by both NiBr2(PPh3) 2/Zn or PdCl2
