893393-33-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 893393-33-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,3,3,9 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 893393-33:
(8*8)+(7*9)+(6*3)+(5*3)+(4*9)+(3*3)+(2*3)+(1*3)=214
214 % 10 = 4
So 893393-33-4 is a valid CAS Registry Number.

Palladium-catalyzed ring enlargement of aryl-substituted methylenecyclopropanes to cyclobutenes
Shi, Min,Liu, Le-Ping,Tang, Jie
, p. 7430 - 7431 (2007/10/03)
Methylenecyclopropanes 1 could be converted to the corresponding cyclobutenes 2 under the catalysis of palladium acetate in the presence of metal bromide in 1,2-dichloroethane under mild conditions. A plausible reaction mechanism has been proposed on the
