86853-68-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 86853-68-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,8,5 and 3 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 86853-68:
(7*8)+(6*6)+(5*8)+(4*5)+(3*3)+(2*6)+(1*8)=181
181 % 10 = 1
So 86853-68-1 is a valid CAS Registry Number.

Synthesis, Regiochemistry, and Reactions of Dichlorocyclobutenones
Hassner, Alfred,Dillon, John L.
, p. 3382 - 3386 (2007/10/02)
Dichlorocyclobutenones previously obtained only with difficulty were prepared by the cycloaddition of dichloroketene with alkynes in the presence of phosphorus oxychloride in fair to good yields.The regiochemistry of addition can be rationalized on the ba
