131026-19-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131026-19-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,0,2 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 131026-19:
(8*1)+(7*3)+(6*1)+(5*0)+(4*2)+(3*6)+(2*1)+(1*9)=72
72 % 10 = 2
So 131026-19-2 is a valid CAS Registry Number.

Control of remote enoate geometry in the bryostatins with a tethered Horner-Wadsworth-Emmons reagent
Evans,Carreira
, p. 4703 - 4706 (1990)
The stereochemistry of the exocyclic unsaturated ester at C13 of the bryostatins may be established with a tethered phosphonate reagent anchored to a proximal hydroxyl function at C16 of an advanced intermediate en route to the total
