Check Digit Verification of cas no

The CAS Registry Mumber 1185906-25-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,5,9,0 and 6 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1185906-25:
(9*1)+(8*1)+(7*8)+(6*5)+(5*9)+(4*0)+(3*6)+(2*2)+(1*5)=175
175 % 10 = 5
So 1185906-25-5 is a valid CAS Registry Number.

Synthesis and single crystal structures of substituted-1,3-selenazol-2-amines

Hua, Guoxiong,Du, Junyi,Slawin, Alexandra M.Z.,Woollins, J. Derek

, (2017)

The synthesis and X-ray single crystal structures of a series of new 4-substituted-1,3- selenazol-2-amines is reported. The efficient preparation of these compounds was carried out by two-component cyclization of the selenoureas with equimolar amounts of α-haloketones. The selenoureas were obtained from the reaction of Woollins' reagent with cyanamides, followed by hydrolysis with water. All new compounds have been characterized by IR spectroscopy, multi-NMR (1H, 13C, 77Se) spectroscopy, accurate mass measurement and single crystal X-ray structure analysis.
