Check Digit Verification of cas no
The CAS Registry Mumber 154870-06-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,8,7 and 0 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 154870-06:
(8*1)+(7*5)+(6*4)+(5*8)+(4*7)+(3*0)+(2*0)+(1*6)=141
141 % 10 = 1
So 154870-06-1 is a valid CAS Registry Number.

Synthesis of α-halo β,γ-unsaturated esters from γ-phenylseleno α,β-unsaturated esters
Duclos, Jean-Francois,Outurquin, Francis,Paulmier, Claude
, p. 7417 - 7420 (1993)
γ-Phenylseleno α,β-unsaturated esters, prepared from α-phenylseleno aldehydes by Horner-Emmons reaction and treated with bromine or sulfuryl chloride, form adducts whose decomposition leads to α-halo β,γ-unsaturated esters in fair to good yields.
