Check Digit Verification of cas no

The CAS Registry Mumber 1250257-11-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,0,2,5 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1250257-11:
(9*1)+(8*2)+(7*5)+(6*0)+(5*2)+(4*5)+(3*7)+(2*1)+(1*1)=114
114 % 10 = 4
So 1250257-11-4 is a valid CAS Registry Number.

Zinc-mediated facile and efficient chemoselective s-alkylation of 5-aryl-1,3,4-oxadiazole-2-thiols in the absence of base

Murty,Rao, Rayudu Venkateswara,Ram, Kesur R.,Reddy, N. Rami,Yadav,Sridhar

experimental part, p. 2914 - 2921 (2010/11/18)

Zinc-mediated facile and efficient chemoselective S-alkylation of 5-aryl 1,3,4-oxadiazole-2-thiols in the presence of a catalytic amount of tetra butyl ammonium iodide was described. The reaction was performed under neutral conditions. The chemoselectivity of the alkylation was confirmed by NMR spectroscopy and x-ray crystallography.
