Check Digit Verification of cas no
The CAS Registry Mumber 1187828-74-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,7,8,2 and 8 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1187828-74:
(9*1)+(8*1)+(7*8)+(6*7)+(5*8)+(4*2)+(3*8)+(2*7)+(1*4)=205
205 % 10 = 5
So 1187828-74-5 is a valid CAS Registry Number.

One-pot synthesis of oxazoles using isocyanide surrogates
Kaim, Laurent El,Grimaud, Laurence,Schiltz, Aurélie
experimental part, p. 5235 - 5237 (2009/12/06)
We wish to present herein a simple one-pot synthesis of 2,5-disubstituted oxazoles, starting from benzyl halides and acyl chlorides. The in situ formation of isocyanides, followed by the addition of an acyl chloride in the presence of a base leads to the
