The CAS Registry Mumber 53218-07-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,2,1 and 8 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 53218-07:
(7*5)+(6*3)+(5*2)+(4*1)+(3*8)+(2*0)+(1*7)=98

Organocatalytic mitsunobu reactions with 3,5-dinitrobenzoic acid

But, Tracy Yuen Sze,Lu, Jinni,Toy, Patrick H.

supporting information; experimental part, p. 1115 - 1117 (2010/06/19)

A second generation procedure for organocatalytic Mitsunobu reactions using 3,5-dinitrobenzoic acid as the pro-nucleophile has been developed. The increased acidity of this acid compared to 4-nitrobenzoic acid, which was used in the original procedure, allowed for higher isolated yields of the desired products and eliminated formation of undesired acetate byproducts.
