118166-99-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118166-99-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,1,6 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 118166-99:
(8*1)+(7*1)+(6*8)+(5*1)+(4*6)+(3*6)+(2*9)+(1*9)=137
137 % 10 = 7
So 118166-99-7 is a valid CAS Registry Number.

INTRAMOLECULAR CYCLOADDITIONS OF MESOIONIC CARBONYL YLIDES
Maier, Martin E.,Evertz, Kaspar
, p. 1677 - 1680 (2007/10/02)
Intramolecular cycloaddition of isomuenchnones, formed by rhodium acetate catalyzed decomposition of N-(diazoacetoacetyl)-alkenylamides, afford highly functionalized cycloadducts with regio- and stereochemical specificity.
