Check Digit Verification of cas no
The CAS Registry Mumber 73300-79-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,3,0 and 0 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 73300-79:
(7*7)+(6*3)+(5*3)+(4*0)+(3*0)+(2*7)+(1*9)=105
105 % 10 = 5
So 73300-79-5 is a valid CAS Registry Number.

SYNTHESIS OF α,β-UNSATURATED SULPHONATES VIA THE WITTIG-HORNER REACTION
Carretero, Juan Carlos,Demillequand, Marc,Ghosez, Leon
, p. 5125 - 5134 (2007/10/02)
A general and practical method of synthesis of α,β-unsaturated sulphonates (25 examples) by the Wittig-Horner reaction is described.Reactions with the salts 2 and carbonyl compounds are not very stereoselective.On the contrary, reactions with esters 1 gave high yields of (E)-α,β-unsaturated sulphonic esters.
Reactions of (Dichlorophosphinyl)methanesulfonyl Chloride
Fild, Manfred,Rieck, Hans-Peter
, p. 142 - 151 (2007/10/02)
Substitution of chlorine by fluorine in (dichlorophosphinyl)methanesulfonyl chloride (2) Cl2P(O)CH2SO2Cl leads to the fluorides F2P(O)CH2SO2X (X = Cl, F); their reactions leading to the fluorophosphorane F4PCH2SO2F and fluorophosphate anions of the type - and - (X = Cl, F) were investigated.Hydrolysis of 2 yields the acid (HO)2P(O)CH2SO2OH, from which esters and amides have been derived.The conversion of the esters to α,β-unsaturated sulfonic acid derivatives via the Horner-Wittig reaction is also described.
