Check Digit Verification of cas no
The CAS Registry Mumber 4730-79-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,3 and 0 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4730-79:
(6*4)+(5*7)+(4*3)+(3*0)+(2*7)+(1*9)=94
94 % 10 = 4
So 4730-79-4 is a valid CAS Registry Number.

Long-chain n-Alkylphosphonic acids, AlkP(O)(OH)2, are synthesized in up to 91 % yield (mostly 40–60 %) by straightforward phosphonylation of alkyl bromides (AlkBr, Alk=C4–C18) with red phosphorus (Pn) in the multiphase KOH/H2O/toluene system in the presence of 2–10 mol % of cetyltrimethylammonium bromide (CTAB), acting as a micellar/phase transfer catalyst and as a generator/transporter of superbasic hydroxide anions, the intermediate potassium phosphinates being in situ oxidized/neutralized by nitric acid. The key steps of the phosphonylation mechanism are the P?P bond cleavage of Pn polymeric molecules by superbasic ?OH anions, dissolved in the CTAB micelles, and phase transfer of polyphosphide anions to the organic phase and their alkylation with AlkBr.
