688045-37-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 688045-37-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,8,0,4 and 5 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 688045-37:
(8*6)+(7*8)+(6*8)+(5*0)+(4*4)+(3*5)+(2*3)+(1*7)=196
196 % 10 = 6
So 688045-37-6 is a valid CAS Registry Number.

Alkene-Directed, Nickel-Catalyzed Alkyne Coupling Reactions
Miller, Karen M.,Luanphaisarnnont, Torsak,Molinaro, Carmela,Jamison, Timothy F.
, p. 4130 - 4131 (2004)
In alkene-directed, nickel-catalyzed coupling reactions of 1,3-enynes with aldehydes and epoxides, the conjugated alkene dramatically enhances reactivity and uniformly directs regioselectivity, independent of the nature of the other alkyne substituent (ar
