207451-24-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 207451-24-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,7,4,5 and 1 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 207451-24:
(8*2)+(7*0)+(6*7)+(5*4)+(4*5)+(3*1)+(2*2)+(1*4)=109
109 % 10 = 9
So 207451-24-9 is a valid CAS Registry Number.

SmI2-mediated sequential radical cyclization/anionic capture of aryl iodides on solid support
Du, Xiaohui,Armstrong, Robert W.
, p. 2281 - 2284 (2007/10/03)
Aryl radicals were generated by SmI2 on solid support, cyclized on to C=C bond, and reduced to their organosamarium anionic species followed by electrophilic capture. However, the capture reaction was substrate-dependant in solution and on soli
