917221-66-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 917221-66-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,7,2,2 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 917221-66:
(8*9)+(7*1)+(6*7)+(5*2)+(4*2)+(3*1)+(2*6)+(1*6)=160
160 % 10 = 0
So 917221-66-0 is a valid CAS Registry Number.

Tandem cyclization of alkynes via rhodium alkynyl and alkenylidene catalysis
Jung, Min Joo,Yuan, Yu,Lee, Chulbom
, p. 14818 - 14819 (2008/02/09)
A rhodium(I)-catalyzed tandem cyclization of alkynes has been developed. The reaction allows for multiple bond formations to occur at both the α- and β-positions of alkynes under mild conditions to yield a variety of fused ring systems as the products. In
