Check Digit Verification of cas no
The CAS Registry Mumber 939411-18-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,9,4,1 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 939411-18:
(8*9)+(7*3)+(6*9)+(5*4)+(4*1)+(3*1)+(2*1)+(1*8)=184
184 % 10 = 4
So 939411-18-4 is a valid CAS Registry Number.

A combination of o-iodoxybenzoic acid (IBX) and a catalytic amount of iodine is found to promote a facile one-pot deacylative sulfonylation reaction of 1,3-dicarbonyl compounds with sodium sulfinates to yield β-carbonyl sulfones. The present method provides the target products bearing a wide variety of functional groups in one step and in good yields.
