144432-91-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144432-91-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,4,3 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 144432-91:
(8*1)+(7*4)+(6*4)+(5*4)+(4*3)+(3*2)+(2*9)+(1*1)=117
117 % 10 = 7
So 144432-91-7 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 (1996)
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.
