877461-78-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 877461-78-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,7,4,6 and 1 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 877461-78:
(8*8)+(7*7)+(6*7)+(5*4)+(4*6)+(3*1)+(2*7)+(1*8)=224
224 % 10 = 4
So 877461-78-4 is a valid CAS Registry Number.

A ring-closing yne-carbonyl metathesis of ynamides
Kurtz, Kimberly C. M.,Hsung, Richard P.,Zhang, Yanshi
, p. 231 - 234 (2007/10/03)
An acid-catalyzed ring-closing ynamide-carbonyl metathesis is described here. This hetero RCM methodology is applicable to the construction of carbocycles as well as heterocycles such as chromenes, quinolizidines, indolizidines, and pyrrolizidines.
