Check Digit Verification of cas no

The CAS Registry Mumber 71893-28-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,8,9 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 71893-28:
(7*7)+(6*1)+(5*8)+(4*9)+(3*3)+(2*2)+(1*8)=152
152 % 10 = 2
So 71893-28-2 is a valid CAS Registry Number.

The stereoselective Horner-Wittig reaction with phoshine oxides: Synthesis of hindered Z alkenes via Luche reduction

Hutton,Jolliff,Mitchell,Warren

, p. 7905 - 7908 (2007/10/02)

The natural anti selectivity of the Horner-Wittig reaction with phospine oxides is reduced when there is a branched chain next to the new C=C double bond. A better approach is Luche reduction of the corresponding ketones which gives high anti selectivity when the branched chain is placed on the side chain next to the phosphine oxide.
