150423-40-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 150423-40-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,0,4,2 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 150423-40:
(8*1)+(7*5)+(6*0)+(5*4)+(4*2)+(3*3)+(2*4)+(1*0)=88
88 % 10 = 8
So 150423-40-8 is a valid CAS Registry Number.

Differentiation of enantiotopic carbonyl groups by the Horner-Wadsworth-Emmons reaction
Tanaka,Ohta,Fuji,Taga
, p. 4071 - 4074 (2007/10/02)
A chiral phosphonoacetate 2 differentiates the enantiotopic carbonyl groups in an α-diketones 5 to afford the Z-olefin 6 in high yield and ee. The absolute stereochemistry of 6 was determined by X-ray analysis of 8 derived from 6.
