56408-09-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 56408-09-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,4,0 and 8 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 56408-09:
(7*5)+(6*6)+(5*4)+(4*0)+(3*8)+(2*0)+(1*9)=124
124 % 10 = 4
So 56408-09-4 is a valid CAS Registry Number.

Cobalt-catalyzed allylzincations of internal alkynes
Yasui, Hiroto,Nishikawa, Toshihiro,Yorimitsu, Hideki,Oshima, Koichiro
, p. 1271 - 1274 (2006)
Cobalt salts such as cobalt(II) chloride catalyze allylzincation reactions of 1-aryl-1-alkynes. The allylzincations proceed in a syn fashion to form 2-allyl-1-aryl-1-alkenylzinc species. Other internal alkynes such as 6-dodecyne or 2-nonyn-1-ol are much l
