157067-44-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 157067-44-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,0,6 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 157067-44:
(8*1)+(7*5)+(6*7)+(5*0)+(4*6)+(3*7)+(2*4)+(1*4)=142
142 % 10 = 2
So 157067-44-2 is a valid CAS Registry Number.

α-Hydroxylation of Cyclic Hydroxamic Acids by Peroxide Oxidation: A Novel Approach to Allelochemicals from Graminae
Hartenstein, Holger,Sicker, Dieter
, p. 4335 - 4338 (1994)
Naturally occurring hemiacetals DIBOA and DIMBOA were synthesized by the first α-hydroxylation of N-hydroxylactams via m-chloroperbenzoic acid oxidation of corresponding cyclosilyl enol ethers.
