128970-60-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128970-60-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,9,7 and 0 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 128970-60:
(8*1)+(7*2)+(6*8)+(5*9)+(4*7)+(3*0)+(2*6)+(1*0)=155
155 % 10 = 5
So 128970-60-5 is a valid CAS Registry Number.

Synthesis of 2-functionalized 1-chloro-1-iodo-1-alkenes from 1-chloro-1-alkynes and IPy2BF4
Barluenga,Rodriguez,Campos
, p. 2751 - 2754 (2007/10/02)
1-Chloro-1-alkynes react with bis(pyridine)iodine(I)tetrafluoroborate (1) and nucleophiles (AcOH, HCOOH, Cl, Br, I) to give, in a regio- and stereoselective addition, 2-functionalized 1-chloro-1-iodo-1-alkenes.
