Check Digit Verification of cas no

The CAS Registry Mumber 31599-46-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,5,9 and 9 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 31599-46:
(7*3)+(6*1)+(5*5)+(4*9)+(3*9)+(2*4)+(1*6)=129
129 % 10 = 9
So 31599-46-9 is a valid CAS Registry Number.

A solvent-free synthesis of (dichloroiodo)arenes from iodoarenes

Zielinska, Agnieszka,Skulski, Lech

, p. 1087 - 1089 (2007/10/03)

An efficient solid-state oxidation of iodoarenes, ArI, is described using the urea-hydrogen peroxide adduct (UHP), a stable, inexpensive, and easily handled oxidant. The reactions were complete in 15min at 85°C. The melts thus obtained were reacted with e

Liquid-phase and biphasic chlorination of some iodoarenes to form (dichloroiodo)arenes with sodium peroxodisulfate as the oxidant

Baranowski,Plachta,Skulski,Klimaszewska

, p. 435 - 437 (2007/10/03)

Liquid-phase and biphasic (CCl4/concd hydrochloric acid) chlorination of some iodoarenes to form the corresponding (dichloroiodo)arenes, prepared in 60-100% crude yields, are reported; dichlorine is produced as follows: Na2S2OP8 + 2 HCl (conc. aq.) → Cl2 + 2 NaHSO4.
