24744-99-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 24744-99-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,7,4 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 24744-99:
(7*2)+(6*4)+(5*7)+(4*4)+(3*4)+(2*9)+(1*9)=128
128 % 10 = 8
So 24744-99-8 is a valid CAS Registry Number.

Synthesis of 2,3-dideuterioesters from 2-halo-3-hydroxyesters by using metallic samarium and diiodomethane
Concellón, José M,Huerta, Mónica
, p. 4943 - 4946 (2007/10/03)
2,3-Dideuterioesters are obtained in high yield from 2-chloro-3-hydroxyesters by a sequenced elimination/reduction process promoted by samarium diiodide generated in situ from metallic samarium and diiodomethane.
