The CAS Registry Mumber 176538-83-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,6,5,3 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 176538-83:
(8*1)+(7*7)+(6*6)+(5*5)+(4*3)+(3*8)+(2*8)+(1*3)=173
173 % 10 = 3
So 176538-83-3 is a valid CAS Registry Number.

Electronic effects on the Z(cis)-selectivity of Horner-Wadsworth-Emmons olefination reaction

Mahipal Reddy,Raj Gopal,Jayathirtha Rao

, p. 312 - 317 (2007/10/03)

Various phosphorates have been synthesized to study the Horner-Wadsworth-Emmons olefination reaction. The phosphoryl stabilised carbanion resulting from phosphonates, carrying electron withdrawing groups attached to phosphorus atom, has been reacted with a variety of aldehydes at - 78°C leading to Z(cis) selective olefination.
