4217-52-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4217-52-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,1 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4217-52:
(6*4)+(5*2)+(4*1)+(3*7)+(2*5)+(1*2)=71
71 % 10 = 1
So 4217-52-1 is a valid CAS Registry Number.

Reduction of diaryl alkenes by hypophosphorous acid-iodine in acetic acid

Fry, Albert J.,Allukian, Myron,Williams, Allison D.

, p. 4411 - 4415 (2002)

A mixture of 50% aqueous H3PO2 and I2 (in catalytic amount) in HOAc efficiently reduces aryl alkenes to the corresponding alkanes in high yield. Addition of acetic anhydride to the medium results in ring-acetylation (or N-acetylation in the case of amines). H3PO2 costs only one-fifth as much as hydriodic acid on a mole basis and one mole of H3PO2 produces four moles of HI, resulting in a 20-fold cost advantage for H3PO2/I2 over aqueous HI as a source of HI.
