The CAS Registry Mumber 190451-98-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,4,5 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 190451-98:
(8*1)+(7*9)+(6*0)+(5*4)+(4*5)+(3*1)+(2*9)+(1*8)=140
140 % 10 = 0
So 190451-98-0 is a valid CAS Registry Number.

Unsaturated nitriles: Precursors for a domino ozonolysis-aldol synthesis of oxonitriles

Fleming, Fraser F.,Huang, Adrian,Sharief, Vaqar A.,Pu, Yifang

, p. 2830 - 2834 (1999)

Cyclic five-, six-, and seven-membered oxonitriles are prepared by a tandem ozonolysis-aldol sequence. Cyclopentenylacetonitrile (4) and cyclohexenylacetonitrile (12) afford the ring-expanded oxonitriles 3 (98%) and 17 (58%), respectively, in highly effic
