Check Digit Verification of cas no
The CAS Registry Mumber 76966-07-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,9,6 and 6 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 76966-07:
(7*7)+(6*6)+(5*9)+(4*6)+(3*6)+(2*0)+(1*7)=179
179 % 10 = 9
So 76966-07-9 is a valid CAS Registry Number.

Cycloadditions of vinylketenes and ethoxyacetylene
Wuest, James D.
, p. 2291 - 2296 (2007/10/02)
Two major adducts are formed when diarylketenes react with ethoxyacetylene: cyclobutenones, produced by 2+2 cycloadditions characteristic of all ketenes, and norcaradienes, the unexpected products of 2+2+2 cycloadditions. Simpler vinylketenes in which the
