Check Digit Verification of cas no

The CAS Registry Mumber 58202-80-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,2,0 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 58202-80:
(7*5)+(6*8)+(5*2)+(4*0)+(3*2)+(2*8)+(1*0)=115
115 % 10 = 5
So 58202-80-5 is a valid CAS Registry Number.

Catalytic synthesis of peptide-derived thiazolines and oxazolines using bis(quinolinolato)dioxomolybdenum(VI) complexes

Sakakura, Akira,Kondo, Rei,Umemura, Shuhei,Ishihara, Kazuaki

, p. 1641 - 1646 (2007)

Bis(2-ethyl-8-quinolinolato)dioxomolybdenum(VI) (9) (1 mol %) shows remarkable catalytic activity for the dehydrative cyclization of cysteine-containing dipeptides 1 to give the corresponding thiazolines 2 with less than 6 % epimerization at the C2-exomet

Molybdenum oxides as highly effective dehydrative cyclization catalysts for the synthesis of oxazolines and thiazolines
