Check Digit Verification of cas no
The CAS Registry Mumber 62881-98-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,8,8 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 62881-98:
(7*6)+(6*2)+(5*8)+(4*8)+(3*1)+(2*9)+(1*8)=155
155 % 10 = 5
So 62881-98-5 is a valid CAS Registry Number.

A general, one-pot method for the synthesis of 2-substituted oxazoles
Williams, Eric L.
, p. 1033 - 1036 (2007/10/02)
The reaction of 2-trimethylsilyl-1,2,3-triazole with acid chlorides readily forms triazole amides. The triazole amides, when heated to 150°C in sulfolane, rearrange with the elimination of nitrogen to give 2-substituted oxazoles in high yields. The oxazol
