289652-63-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 289652-63-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,6,5 and 2 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 289652-63:
(8*2)+(7*8)+(6*9)+(5*6)+(4*5)+(3*2)+(2*6)+(1*3)=197
197 % 10 = 7
So 289652-63-7 is a valid CAS Registry Number.

Cyclization of alkenyl radicals in 5- and 6-(π-exo)-exo-dig modes: New entry to exo-cyclic dienes
Sha, Chin-Kang,Zhan, Zhuang-Ping,Wang, Fu-Shing
, p. 2011 - 2013 (2007/10/03)
matrix presented Radical cyclizations of alkenyl iodides in both 5- and 6-(π-exo)-exo-dig modes were effected by tributyltin hydride and AIBN to give exo-cyclic dienes fused to five- and six-membered rings in good yields.
