212504-69-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 212504-69-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,2,5,0 and 4 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 212504-69:
(8*2)+(7*1)+(6*2)+(5*5)+(4*0)+(3*4)+(2*6)+(1*9)=93
93 % 10 = 3
So 212504-69-3 is a valid CAS Registry Number.

Synthesis of γ-hydroxy α,β-unsaturated amides by base induced isomerization of epoxy amides
Brooks, Peter B.,Marson, Charles M.
, p. 9613 - 9622 (2007/10/03)
Treatment of 3,4-epoxyamides with LDA affords γ-hydroxy-α,β- unsaturated amides, usually with high (E)-selectivity. The 3,4-epoxyamides were prepared by the epoxidation of β,γ-unsaturated amides with meta- chloroperbenzoic acid.
