126459-74-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126459-74-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,4,5 and 9 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 126459-74:
(8*1)+(7*2)+(6*6)+(5*4)+(4*5)+(3*9)+(2*7)+(1*4)=143
143 % 10 = 3
So 126459-74-3 is a valid CAS Registry Number.

Electrophilic Additions of Positive Iodine to Alkynes through an Iodonium Mechanism
Barluenga, Jose,Rodriguez, Miguel A.,Campos, Pedro J.
, p. 3104 - 3106 (2007/10/02)
Alkynes react with bis(pyridine)iodonium (I) tetrafluoroborate (1) and nucleophiles (CH3COOH, HCOOH, Cl-, pyridine, Br-, I-) to give 1,2 iodofunctionalized alkenes.The regiochemistry of the processes is in accordance with
