Check Digit Verification of cas no
The CAS Registry Mumber 21944-98-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,4 and 4 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 21944-98:
(7*2)+(6*1)+(5*9)+(4*4)+(3*4)+(2*9)+(1*8)=119
119 % 10 = 9
So 21944-98-9 is a valid CAS Registry Number.

A novel synthesis of γ,δ-unsaturated aldehydes from α-formyl-γ-lactones
Snowden, Roger L.,Brauchli, Robert,Linder, Simon
experimental part, p. 1216 - 1225 (2011/09/16)
A preparatively useful one-step transformation of γ,γ- disubstituted α-formyl-γ-lactones into trisubstituted γ,δ-unsaturated aldehydes is described, by means of catalytic amounts of either AcOH or AcOEt in the vapor phase over a glass support. A mechanistic rationale is proposed. Copyright
