Check Digit Verification of cas no

The CAS Registry Mumber 70209-12-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,2,0 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 70209-12:
(7*7)+(6*0)+(5*2)+(4*0)+(3*9)+(2*1)+(1*2)=90
90 % 10 = 0
So 70209-12-0 is a valid CAS Registry Number.

Synthesis of tetrazole-fused glycosides by a tandem fragmentation- cyclization reaction

Paz, Nieves R.,Santana, Andrés G.,Francisco, Cosme G.,Suárez, Ernesto,González, Concepción C.

supporting information; experimental part, p. 3388 - 3391 (2012/08/28)

The fragmentation of anomeric alkoxyl radicals (ARF) and the subsequent intramolecular cyclization promoted by hypervalent iodine reagents provide an excellent method for the synthesis of tetrazolo-sugars. This new reaction offers additional advantages for the synthesis of these compounds, including the ready availability of the starting materials, experimental simplicity, mild conditions, and good yields.
