74643-89-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74643-89-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,6,4 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 74643-89:
(7*7)+(6*4)+(5*6)+(4*4)+(3*3)+(2*8)+(1*9)=153
153 % 10 = 3
So 74643-89-3 is a valid CAS Registry Number.

PALLADIUM(O) CATALYZED REACTION OF 1,3-DIENE 1,4-EPIPEROXIDES
Suzuki, M.,Oda, Y.,Noyori, R.
, p. 4413 - 4416 (2007/10/02)
Reaction of 1,3-diene 1,4-epiperoxides with Pd(PPh3)4 catalyst forms the corresponding 4-hydroxy enones, syn diepoxides, and 1,4-diols as the major products.The results are interpreted as being due to competing Pd(O)/ Pd(II) and Pd(O)/ Pd(I) exchange mechanisms.
