Check Digit Verification of cas no

The CAS Registry Mumber 126114-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,1,1 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 126114-20:
(8*1)+(7*2)+(6*6)+(5*1)+(4*1)+(3*4)+(2*2)+(1*0)=83
83 % 10 = 3
So 126114-20-3 is a valid CAS Registry Number.

ORGANOSULPHUR COMPOUNDS XLVII ALKYLATION OF SULPHINIC ACIDS BY O-ALKYLISOUREAS: O-VERSUS S-REACTIVITY AND ASYMMETRIC SYNTHESIS OF ALKYL SULPHINATES

Kielbasinski, Piotr,Zurawinski, Remigiusz,Drabowitz, Jozef,Mikolajczyk, Marian

, p. 6687 - 6692 (2007/10/02)

The reaction of O-alkylisoureas with sulphinic acids was found to produce the corresponding sulphones and sulphinates, the latter being predominantly formed.The sulphinate to sulphone ratio is strongly influenced by the kind of alkyl groups in the O-alkylisourea and appeared to be also dependent on the solvent used.A few optically active sulphinates (e.e. up to 8.1percent) were prepared in the reaction between benzenesulphinic acid and a series of O-alkylisoureas bearing optically active substituents at the nitrogen atom.A possible reaction mechanism is discussed.
