20997-50-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 20997-50-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,9,9 and 7 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20997-50:
(7*2)+(6*0)+(5*9)+(4*9)+(3*7)+(2*5)+(1*0)=126
126 % 10 = 6
So 20997-50-6 is a valid CAS Registry Number.

An efficient rearrangement of secondary alkyl S-methyl xanthates by trimethylaluminum (TMA)
Barton, Derek H. R.,Choi, Seung-Yong
, p. 2695 - 2698 (2007/10/03)
The rearrangement of secondary S-methyl xanthates to S-methyl dithiocarbonates at room temperature using trimethylaluminum has been studied. This reaction affords an efficient and simple method for converting secondary alcohols to thiols.
