Check Digit Verification of cas no

The CAS Registry Mumber 54901-54-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,9,0 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 54901-54:
(7*5)+(6*4)+(5*9)+(4*0)+(3*1)+(2*5)+(1*4)=121
121 % 10 = 1
So 54901-54-1 is a valid CAS Registry Number.

Synthesis of [thiazolium-2,2′-14C2]-SAR97276A from [14C]-thiourea

Herbert, John M.,Le Strat, Franck,Oumeddour, Delphine G.,Passey, Stephen C.,Taylor, Keith,Whitehead, David M.

, p. 89 - 92 (2011)

[thiazolium-2,2′-14C2]-SAR97276A, a bis(thiazolium) antimalarial development candidate, was synthesized from [ 14C]-thiourea with an overall radiochemical yield of 15%. The synthetic route involves a modified procedure for the synthesis of [ 14C]-sulfurol, also a key intermediate in thiamine synthesis, which was developed due to unlabelled chemistry proving irreproducible with the radiolabelled substrate.
