92177-76-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 92177-76-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,1,7 and 7 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 92177-76:
(7*9)+(6*2)+(5*1)+(4*7)+(3*7)+(2*7)+(1*6)=149
149 % 10 = 9
So 92177-76-9 is a valid CAS Registry Number.

Cycloadditions, III. - Reactions of Ynamines with Silylketenes
Himbert, Gerhard,Henn, Lothar
, p. 1358 - 1366 (2007/10/02)
The ynamines 1a-e react with the silyl aldoketenes 2a and b in a normal way under cycloaddition to give the allenecarboxamides 6 and in one case a cyclobutenone derivative.The presence of the silyl group in the adducts gives rise to 1,3-migrations of
