93578-98-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 93578-98-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,5,7 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 93578-98:
(7*9)+(6*3)+(5*5)+(4*7)+(3*8)+(2*9)+(1*8)=184
184 % 10 = 4
So 93578-98-4 is a valid CAS Registry Number.

SYNTHESIS OF ESTERS BY RHODIUM(I) CATALYZED BORATE ESTER-BENZYLIC BROMIDE CARBONYLATION REACTIONS
Woell, James B.,Alper, Howard
, p. 3791 - 3794 (2007/10/02)
Benzylic halides react with trialkylborates and carbon monoxide, in the presence of 1,5-hexadienerhodium chloride dimer, to give esters in excellent yields.The reaction is applicable to the synthesis of primary, secondary and even tertiary esters.
