1000992-80-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1000992-80-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,0,9,9 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1000992-80:
(9*1)+(8*0)+(7*0)+(6*0)+(5*9)+(4*9)+(3*2)+(2*8)+(1*0)=112
112 % 10 = 2
So 1000992-80-2 is a valid CAS Registry Number.

Gold-catalyzed intramolecular carbocyclization of alkynyl ketones leading to highly substituted cyclic enones
Jin, Tienan,Yamamoto, Yoshinori
, p. 5259 - 5262 (2008/09/17)
(Chemical Equation Presented) The reaction of the internal alkynyl ketones 1 (n = 1) under the combined catalyst, AuCl3 and AgSbF6, gave the enones 2 in good to high yields, whereas that of the terminal alkynyl ketones 1 (n = 0) unde
