74038-34-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74038-34-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,0,3 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 74038-34:
(7*7)+(6*4)+(5*0)+(4*3)+(3*8)+(2*3)+(1*4)=119
119 % 10 = 9
So 74038-34-9 is a valid CAS Registry Number.

Chiral, non-racemic α-hydroxyphosphonates and phosphonic acids via stereoselective hydroxylation of diallyl benzylphosphonates
Skropeta, Danielle,Schmidt, Richard R.
, p. 265 - 273 (2007/10/03)
Chiral, non-racemic α-hydroxyphosphonates have been prepared in high enantiomeric excess (96-98% ee), via stereoselective oxaziridine-mediated hydroxylation of diallyl benzylphosphonates. The enantiomeric purity and absolute configuration of the α-hydroxy
