Check Digit Verification of cas no

The CAS Registry Mumber 244076-19-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,4,0,7 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 244076-19:
(8*2)+(7*4)+(6*4)+(5*0)+(4*7)+(3*6)+(2*1)+(1*9)=125
125 % 10 = 5
So 244076-19-5 is a valid CAS Registry Number.

A convergent, stereocontrolled synthesis of C2-symmetrical and pseudosymmetrical sulfur-tethered bis(amino alcohols)

Aguilar, Nuria,Moyano, Albert,Pericas, Miquel A.,Riera, Antoni

, p. 3913 - 3916 (1999)

The totally enantiocontrolled preparation of C2-symmetrical and pseudosymmetrical sulfur-tethered bis(amino alcohols) from anti-3-amino-1,2- alkane diols is described. The key step in the synthetic procedure involves the use of triphenylsilanethiol as a sulfide or hydrogenosulfide equivalent in the regioselective nucleophilic ring opening of both anti- and syn- aminoalkyl epoxides.
