Check Digit Verification of cas no

The CAS Registry Mumber 1126639-14-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,6,6,3 and 9 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1126639-14:
(9*1)+(8*1)+(7*2)+(6*6)+(5*6)+(4*3)+(3*9)+(2*1)+(1*4)=142
142 % 10 = 2
So 1126639-14-2 is a valid CAS Registry Number.

A novel and convenient synthesis of cyclopent-1-enecarboxylates by an intramolecular Horner-Wadsworth-Emmons reaction

Krawczyk, Henryk,Albrecht, Lukasz

experimental part, p. 3951 - 3956 (2009/06/05)

A general and efficient method for the preparation of 2-diethoxyphosphoryl- 6-oxohexanoates is presented. This approach is based on the Michael addition of [2-(1,3-dioxolan-2-yl)ethyl]magnesium bromide to various 3-substituted tert-butyl (E)-2-(diethoxyphosphoryl)alk-2-enoates as a key step. Application of the 2-diethoxyphosphoryl-6-oxohexanoates obtained in the intramolecular Horner-Wadsworth-Emmons reaction for the preparation of 5-substituted tert-butyl cyclopent-1-enecarboxylates is also reported.
