187458-83-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 187458-83-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,4,5 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 187458-83:
(8*1)+(7*8)+(6*7)+(5*4)+(4*5)+(3*8)+(2*8)+(1*3)=189
189 % 10 = 9
So 187458-83-9 is a valid CAS Registry Number.

Application of silacyclic allylsilanes to the synthesis of β-hydroxy-δ-lactones: synthesis of Prelactone B
Sellars, Jonathan D.,Steel, Patrick G.
, p. 5588 - 5595 (2009)
Silacyclic allylsilanes generated through a silene-diene Diels-Alder cycloaddition represent versatile bifunctional reagents for organic synthesis. This is demonstrated in a short stereocontrolled synthesis of (±)-Prelactone B.
